RECOMMENDED: Click here to fix Windows errors and optimize system performance

Some users have reported receiving errors associated with the MSVcr90.dll file. The most reported error occurrences are “MSVCR90.dll Not Found” and “MSVCR90.dll is missing“.  These are typically encountered at startup or when the user tries to open a Microsoft Office application. This is quite a common occurence on computers that have been recently upgraded from Windows 7 to Windows 10.

However, this error is also commonly reported with Adobe products like Photoshop and Illustrator or when opening certain games that require an optional DLL library that was not installed with the game.

Depending on which application is displaying the MSVCR90.dll error and your Windows version, you might encounter it in several different formats. Here’s a shortlist with other common error messages:

  • “This application failed to start because msvcr90.dll was not found. Reinstalling the application may fix this problem.”
  • “Cannot find *Path to DLL* \msvcr90.dll”
  • “Cannot start *Application*.  A required component is missing: msvcr90.dll. Please install *Application* again.”

What is MSVCR90.DLL?

MSVCR90.DLL is part of an optional update of the Visual C++ redistributable. The mSVCR90.dll file is a DLL (Dynamic Link Library) that is commonly used by programs made in Microsoft Visual C++ 2008.

Given the fact that the Microsoft Visual C++ 2008 application development framework is fairly old, the mSVCR90.dll file is quite uncommon among newly released applications. However, if you currently have installed many applications (or games) that are fairly old, you might have multiple copies of the same mSVCR90.dll spread around on your computer.

If you’re currently struggling with a mSVCR90.dll error, the methods featured in this article will help. Below you have a collection of potential fixes that users in a similar situation have used to resolve the issue. Please follow each potential fix in order until you find a method that resolves the mSVCR90.dll error in your particular situation.

Method 1: Installing the missing Visual C++ Redist Package

Before you do anything else, it’s important to make sure that you actually have the application development framework that contains the MSVCR90.dll file installed on your computer. Installing the Microsoft Visual C++ 2008 Redistributable Package will enable you to verify whether the error was occurring because you were missing this dynamic link library file.

Here’s a quick guide on installing the required Microsoft Visual C++ 2008 Redist Package:

  1. Visit this link (here), select your language and click the Download button.
  2. Wait until the download is complete, then open the vcredist_86.exe installer. Hit Yes at the UAC (User Account Control) prompt and then follow the on-screen prompts to install the missing redist package.
    Note: If the redistributable package is already installed, choose Uninstall to remove the current version from your computer. Then, open the installer again and follow the prompts to install the Microsoft Visual C++ 2008 Redistributable Package again. Some users have reported that this managed to resolve MSVCR90.dll errors caused by corrupted files.
  3. Once the redistributable package is installed, reboot your computer manually if not automatically prompted to do so. At the next startup, open the application that was previously showing an error associated with the MSVCR90.dll file and see if the issue has been resolved. If you’re still seeing the same error message, move down to Method 2.

Method 2: Repairing the application that is failing (if applicable)

Some users have managed to resolve the issue after repairing the application that was displaying the MSVCR90.dll error. This method is very effective with failing applications from the Microsoft Office suite, but will not be applicable to some programs that don’t have repair strategies. This will accomplish the purpose of replacing the MSVCR90.dll file in case it was corrupted, thus resolving the problem.

Note: Keep in mind that depending on the program that displays the error, you might be required to insert the installation media in order to perform the repairs.

Below you have a guide with the steps required to take in order to repair a broken program belonging to the Microsoft Office Suite. The exact steps might be different if you’re encountering the issue with a different program:

PRO TIP: If the issue is with your computer or a laptop/notebook you should try using the Reimage Plus Software which can scan the repositories and replace corrupt and missing files. This works in most cases, where the issue is originated due to a system corruption. You can download Reimage Plus by Clicking Here
  1. Press Windows key + R to open up a Run box. Then, type “appwiz.cpl” and hit Enter to open Programs and Features.
  2. In Programs and Features, right-click on the Microsoft Office suite (or other application and click on Change.
  3. In the next menu, choose Repair and follow the on-screen prompts to reinitiate the components that were causing the issue (including MSVCR90.dll).
  4. Once the repair is complete, reboot your computer. At the next startup, open the application again and see if the issue resurfaces.

If you’re still encountering the same issue or this method wasn’t applicable, move down to Method 3.

Method 3: Removing Badly copied plugins on Photoshop and Illustrator (if applicable)

If you encounter this issue while trying to open Photoshop, Illustrator or another Adobe product, you might want to see if you installed any plugins. Users encountering the same problem have reported that plugins are a typical cause for triggering  MSVCR90.dll errors on photo editing Adobe programs such as Photoshop and Illustrator.

This typically happens when the users try to migrate a plug-in from an older program version to a new one. The error occurs because most plugins will install additional files in the main photoshop folders (such as the MSVCR90.dll) that will not get carried over if the user moves the plug-in manually.

To verify if this is the cause of the issue, remove all the plug-in files that you copied manually and then use the installer to install the plugins. Once the installation is complete, reboot your computer and see if the issue has been resolved at the next startup.

If this method was not applicable or didn’t fix the problem, move down to the other method below.

Method 4: Uninstalling Security Update for Microsoft Excel 2010 (KB3085609)

If you’re getting the MSVCR90.dll is missing error specifically with Excel 2010, the problem is most likely caused by a bug in one security update (KB3085609). Users encountering the same problem have managed to eliminate the issue and open Excel after uninstalling the Security Update for Microsoft Excel 2010 (KB3085609) 32-Bit Edition.

Supposedly, this security updates is not only crashing Excel 2010 but also newer Excel version.

Here’s a quick guide on how to uninstall the KB3085609 security update and prevent it from installing again:

  1. Press Windows key + R to open up a Run box. Then, type “appwiz.cpl” and hit Enter to open Programs and Features.
  2. In Programs and Features, use the left-hand side pane to click on Installed Updates.
  3. Next, in the list of installed updates, searched for Security Update for Microsoft Excel 2010 (KB3085609) 32-Bit Edition. Once you find it, right-click and choose Uninstall, then follow the on-screen prompts to remove it from your computer.
  4. Reboot your computer and see if you are now able to open Excel at the next startup. If you are, you’ve just managed to identify the culprit.

Even if the problem is fixed right now, the issue will return if you leave it like this. WU (Windows Update) will automatically re-install the update unless you block it. In order to block the KB3085609 from installing again, you need to install the “Show or hide updates” troubleshooter. Once you download it, open it and hit the Next, then wait for the investigation to complete. Then, click on Hide updates, check the box associated with the KB3085609 update and hit Next to hide it.
