Some Windows users are reporting that they are seeing the “Error 87 the Parameter is Incorrect” error every time they try to open an application. In some cases, the encountered error message is: “LoadLibrary failed with error 87: The parameter is incorrect.” Some affected users are reporting that the issue only occurs with one or two applications while other users report that the error pops up with virtually any application that they try to open. The issue is not exclusive to a certain Windows version as it’s confirmed to appear on Windows 7, Windows 8 and Windows 10.
What is causing the “Error 87 the Parameter is Incorrect” error?
We investigated this particular issue by looking at various user reports and the repair strategies that are commonly being used to solve this particular problem. Based on what we gathered, there are several different potential culprits that have the potential of causing this issue:
- Software conflict is causing the issue – There are certain applications or 3rd party services that are known to trigger this particular issue if they end up conflicting with the display drivers. If this scenario is applicable, you can identify the culprit responsible by performing a clean boot and systematically re-enabling the disabled items.
- System file corruption – Corrupted system files can also be responsible for the apparition of this particular issue. Several users encountering this exact issue have reported that the issue was completely resolved after performing a CHKDSK, an SFC or a DISM scan.
- Corrupted or improper display drivers – Corrupted, improper or incomplete display drivers can also cause this particular issue. Especially if they end up conflicting with a dedicated driver. If this scenario is applicable, you can resolve the issue by either rolling back the river or forcing your OS to install a newer version.
- Corrupted Windows Update Service – Another fairly common culprit is a corrupted Windows Update service. Chances are the default values have been modified to the point where the entry has become corrupted. IN this case, you can resolve the issue by restoring the Windows Update service to the default values.
- Split-tunneling is disabled – If the error message is encountered while you try to open a VPN application or you’re performing something dependable to it, it’s probably because split tunneling is disabled. If this scenario is applicable, you can resolve the issue by using Powershell to enable split tunneling.
- Messaging Service cannot be disabled conventionally – As it turns out, the Messaging service is known to trigger this particular issue when the user tries to disable it conventionally on Windows 10. In this case, you can resolve the problem by using the Registry Editor to disable it.
- A DLL file is halting the opening of the video editing program – There’s one recurring problem with ATI graphics card users that are trying to open video editing programs like Sony Vega or similar. If you’re seeing the error message in this scenario, you can resolve the issue by forcing your OS to ignore the file.
In case you’re trying to fix the same exact issue, this article will provide you with several repair strategies. Down below, you’ll find a collection of methods that other users in a similar situation have successfully used to fix this particular issue.
For the best results, we encourage you to follow the methods below in the order that they are presented since they are ordered by efficiency and severity. Eventually, you should stumble upon a method that will resolve the issue regardless of the culprit that is causing the problem.
Method 1: Performing a Clean Boot
Performing a clean boot will start Windows with the minimal set of drivers and startup programs. This procedure will help us figure out if the issue is caused by some sort of software conflict that occurs when the “Error 87 the Parameter is Incorrect” message appears.
Several affected users that we’re also looking for a way to fix the issue have reported that the error stopped occurring while they were in a clean boot state. Once they confirmed that an application or a driver was producing the error message, they proceeded to strip down installed software component until the issue was no longer occurring even when Windows booted up normally.
Here’s a quick guide on performing a clean boot an figure out the software culprit that is triggering the error message:
- First things first, ensure that you are signed in with a user that has administrative privileges.
- Press Windows key + R to open up a Run dialog box. Next, type “msconfig” inside the text box and press Enter to open up the System Configuration window. When prompted by the UAC (User Account Control), click Yes to grant administrative privileges.
- Inside the System Configuration window, select the Services tab from the ribbon bar at the top and start by checking the box associated with Hide all Microsoft services. Then, turn your attention to the remaining services above and hit the Disable all button to prevent any 3rd party services to be enabled at the next system startup.
- After you hit Apply to save the changes, select the Startup tab and click on Open Task Manager.
- From the Startup tab of Task Manager, select each service individually and then click on Disable to prevent it from running at the next system startup.
- Once all necessary items have been disabled, close Task Manager and restart your computer.
- At the next system startup, your machine will boot into a Clean Boot State.
- Repeat the action that was previously triggering the “Error 87 the Parameter is Incorrect” and see if the issue has been resolved.
- If the procedure was successful, revisit step 3 and 5 and systematically re-enable the startup items & services that you disabled coupled with reboots until you discover your culprit.
If this method didn’t resolve the issue for you, move down to the next method below.
Method 2: Performing a CHSDSK, SFC & DISM scan
As it turns out, this particular issue can also be caused by system file corruption that might end up messing with the display drivers. Several users struggling to resolve the same issue have reported that the issue was resolved after they performed a CHKDSK, SFC or a DISM scan. These are two built-in utilities that are known to fix a lot of system-file related issues.
Here’s a quick guide doing this on any Windows computer:
- Once you’re ready to initiate the scan, press Windows key + R to open up a Run dialog box. Then, type “cmd” and press Ctrl + Shift + Enter to open up an elevated Command Prompt
Note: When you’re prompted by the UAC (User Account Control), click Yes to grant administrative privileges.
- Inside the elevated Command Prompt, type the following command and press Enter to initiate a CHKDSK scan:
chkdsk X: /r Important: X is simply a placeholder. Replace it with the letter of the drive you are trying to target.
Note: A CHKDSK scan will scan your entire drive looking for integrity violations and logical errors. If any inconsistencies are found, the utility will attempt to fix these problems by repairing soft bad sectors and ensuring that hard bad sectors are never used again.
- Once the scan is complete, restart your machine and see if the issue is resolved at the next system startup. If the same error is still occurring, move down to the next step below.
- Follow Step 1 again to open up another elevated Command Prompt. Then, type the following command and press Enter to initiate an SFC scan:
Note: The System File Checker (SFC) utility will scan all protected system files and replace any corrupted files that it manages to find with locally stored copies located in a compressed folder (exact location is (%WinDir%\System32\dllcache)
- Once the procedure is complete, restart your computer and see if the issue is resolved at the next system startup.
- If you’re still encountering the issue, follow Step 1 once again to open another elevated Command Prompt. Then, type the following command and press Enter to initiate a DISM (Deployment Image Servicing and Management) scan:
DISM.exe /Online /Cleanup-image /Restorehealth
Note: A DISM scan uses Windows Update to fetch the files required to fix the corrupted occurrences that are identified. That’s why is important to ensure that you have a stable internet connection before performing this last step.
- Once the procedure is complete, restart your computer and see if the issue has been resolved at the next system startup.
If the same “Error 87 the Parameter is Incorrect” error is still occurring, move down to the next method below.
Method 3: Rolling back (Uninstalling) the display drivers
As it turns out, this particular issue can also be caused by a corrupted or incomplete display driver. Some users that have been encountering this exact issue have reported that the issue stopped occurring after they used Device Manager to roll back the display driver (or uninstalling the driver) if no rollback action was available.
Doing so will not have a long-lasting effect on your computer since Windows 10 is equipped to install any missing drivers back on your computer.
Here’s a quick guide on rolling back or uninstalling the display drivers:
- Press Windows key + R to open up a Run dialog box. Then, type “devmgmt.msc” and press Enter to open up Device Manager.
- Inside Device Manager, expand the drop-down menu associated with Display Adapters.
- Next, right-click on your display adapter and choose Properties from the context menu.
Note: If you have two different display drivers ( a dedicated and integrated option), it’s preferable that you deal with both.
- Inside the Properties screen, go to the Driver tab and click on Roll Back Driver. Then, follow the on-screen prompts to complete the process.
Note: If the Roll Back Driver version is unavailable, click on Uninstall Device instead.
- Once the process is complete, restart your computer. At the next system startup, your OS will complete the installation. If the driver was previously uninstalled, Windows will automatically search for and install the latest driver version.
- Now that the display driver has been modified, repeat the action that was previously triggering the “Error 87 the Parameter is Incorrect” error and see if the issue is still occurring.
If the same error is still occurring, move down to the next method below.
Method 4: Restoring the Windows Update Service
If you’re getting the “Error 87 the Parameter is Incorrect” error while trying to start the Windows Update service, chances are the default services have been modified to the point where some entries have become corrupted.
Several users encountering this exact issue have reported that they managed to fix the issue indefinitely after following the steps necessary to restore to the default services and the settings.
Important: The steps below are only applicable to Windows 10.
Here’s a quick guide on restoring the Windows Update service:
- Press Windows key + R to open up a Run dialog box. Then, type “notepad” and press Enter to open up the default text editor.
- Inside the Notepad utility, paste the following code:
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv] "PreshutdownTimeout"=dword:036ee800 "DisplayName"="@%systemroot%\\system32\\wuaueng.dll,-105" "ErrorControl"=dword:00000001 "ImagePath"=hex(2):25,00,73,00,79,00,73,00,74,00,65,00,6d,00,72,00,6f,00,6f,00,\ 74,00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,73,\ 00,76,00,63,00,68,00,6f,00,73,00,74,00,2e,00,65,00,78,00,65,00,20,00,2d,00,\ 6b,00,20,00,6e,00,65,00,74,00,73,00,76,00,63,00,73,00,00,00 "Start"=dword:00000003 "Type"=dword:00000020 "Description"="@%systemroot%\\system32\\wuaueng.dll,-106" "DependOnService"=hex(7):72,00,70,00,63,00,73,00,73,00,00,00,00,00 "ObjectName"="LocalSystem" "ServiceSidType"=dword:00000001 "RequiredPrivileges"=hex(7):53,00,65,00,41,00,75,00,64,00,69,00,74,00,50,00,72,\ 00,69,00,76,00,69,00,6c,00,65,00,67,00,65,00,00,00,53,00,65,00,43,00,72,00,\ 65,00,61,00,74,00,65,00,47,00,6c,00,6f,00,62,00,61,00,6c,00,50,00,72,00,69,\ 00,76,00,69,00,6c,00,65,00,67,00,65,00,00,00,53,00,65,00,43,00,72,00,65,00,\ 61,00,74,00,65,00,50,00,61,00,67,00,65,00,46,00,69,00,6c,00,65,00,50,00,72,\ 00,69,00,76,00,69,00,6c,00,65,00,67,00,65,00,00,00,53,00,65,00,54,00,63,00,\ 62,00,50,00,72,00,69,00,76,00,69,00,6c,00,65,00,67,00,65,00,00,00,53,00,65,\ 00,41,00,73,00,73,00,69,00,67,00,6e,00,50,00,72,00,69,00,6d,00,61,00,72,00,\ 79,00,54,00,6f,00,6b,00,65,00,6e,00,50,00,72,00,69,00,76,00,69,00,6c,00,65,\ 00,67,00,65,00,00,00,53,00,65,00,49,00,6d,00,70,00,65,00,72,00,73,00,6f,00,\ 6e,00,61,00,74,00,65,00,50,00,72,00,69,00,76,00,69,00,6c,00,65,00,67,00,65,\ 00,00,00,53,00,65,00,49,00,6e,00,63,00,72,00,65,00,61,00,73,00,65,00,51,00,\ 75,00,6f,00,74,00,61,00,50,00,72,00,69,00,76,00,69,00,6c,00,65,00,67,00,65,\ 00,00,00,53,00,65,00,53,00,68,00,75,00,74,00,64,00,6f,00,77,00,6e,00,50,00,\ 72,00,69,00,76,00,69,00,6c,00,65,00,67,00,65,00,00,00,00,00 "FailureActions"=hex:80,51,01,00,00,00,00,00,00,00,00,00,03,00,00,00,14,00,00,\ 00,01,00,00,00,60,ea,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv\Parameters] "ServiceDll"=hex(2):25,00,73,00,79,00,73,00,74,00,65,00,6d,00,72,00,6f,00,6f,\ 00,74,00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,\ 77,00,75,00,61,00,75,00,65,00,6e,00,67,00,2e,00,64,00,6c,00,6c,00,00,00 "ServiceDllUnloadOnStop"=dword:00000001 "ServiceMain"="WUServiceMain" [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv\Security] "Security"=hex:01,00,14,80,78,00,00,00,84,00,00,00,14,00,00,00,30,00,00,00,02,\ 00,1c,00,01,00,00,00,02,80,14,00,ff,00,0f,00,01,01,00,00,00,00,00,01,00,00,\ 00,00,02,00,48,00,03,00,00,00,00,00,14,00,9d,00,02,00,01,01,00,00,00,00,00,\ 05,0b,00,00,00,00,00,18,00,ff,01,0f,00,01,02,00,00,00,00,00,05,20,00,00,00,\ 20,02,00,00,00,00,14,00,ff,01,0f,00,01,01,00,00,00,00,00,05,12,00,00,00,01,\ 01,00,00,00,00,00,05,12,00,00,00,01,01,00,00,00,00,00,05,12,00,00,00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv\TriggerInfo] [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv\TriggerInfo\0] "Type"=dword:00000005 "Action"=dword:00000001 "Guid"=hex:e6,ca,9f,65,db,5b,a9,4d,b1,ff,ca,2a,17,8d,46,e0 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv\TriggerInfo\1] "Type"=dword:00000005 "Action"=dword:00000001 "Guid"=hex:c8,46,fb,54,89,f0,4c,46,b1,fd,59,d1,b6,2c,3b,50

- Next, set the Base to Hexadecimal and then set the Value data to 4 (Disabled).
- Close the Registry Editor, restart your computer and see if the issue is resolved at the next system startup.
If the issue is still occurring, move down to the next method below.
Method 7: Renaming the atig6pxx.dll file
If you’re encountering the “Error LoadLibrary failed with error 87: The parameter is incorrect error” when trying to open Vegas Pro or a similar editing program and you have an ATI graphics card, you are probably suffering from a recurring problem that has affected a lot of users in a similar situation.
Several users that have been encountering this exact issue have reported that they have managed to solve it by modifying a DLL file named atig6pxx.dll. After doing this, they reported that they were able to open the editing program that was previously failing with this particular error.
Here’s what you need to do:
- Use the search function on your Windows taskbar to search for “atig6pxx.dll”. You can press Windows key + S to bring up the Search function instantly.
- From the list of results, right-click on atig6pxx.dll and choose Open File Location. It should lead you directly into the System32 folder.
- Next, right-click on the atig6pxx.dll file and choose Rename. Then, simply add the .bak extension at the end of the .dll extension. This will essentially instruct your OS to ignore this file. Click Yes at the confirmation prompt, then click Yes once again if you’re prompted by the UAC (User Account Control).
Note: If the extensions are not visible from the get-go, go to the ribbon bar at the top of the File Explorer window, click on View and ensure that the box associated with File name extensions is enabled.
- Once this modification is complete, restart your computer and see if the issue is still occurring when you launch a video editing software.
