Fix: LogiLDA.dll is Missing

LogiDLA.dll is the DLL file related to Logitech Download Assistant. Users face the error when the DLL file is either missing from their computer or cannot be started. This mostly happens when they upgrade from Windows 7 to Windows 10. As we all know, Windows tries to preserve your files and settings whenever you update the operating system and the remnants of this software get left in the system. This error pops up mostly during startup of your computer.

Problems with Logitech Download Assistant are nothing new and people prefer to remove the application altogether. Since you can already download the software for their hardware directly through the website, the hassle of seeing error messages each day isn’t worth it.

Solution 1: Disabling LogiDA from Startup

Logitech Download Assistant, like other programs, tend to start up automatically whenever you boot your computer. It searches for updates in the background while also impacting your CPU during the crucial moments of the startup. A simple workaround if the system doesn’t have the DLL file is to stop the software from starting itself using the task manager.

  1. Press Windows + R, type “taskmgr” in the dialogue box and press Enter.
  2. Once in the task manager and navigate to the startup tab. Now look for the software “LogiDA” from the list, right-click it and select “Disable”.

  1. Restart your computer. Notice that the software will be disabled to startup when your computer boots but this is only a temporary solution. We need to edit some keys in your registry for the effect to be permanent. Press Windows + R, type “regedit” in the dialogue box and press Enter.
  2. Navigate to the following file path:


  1. Locate the key “Logitech Download Assistant”. Right-click it and press Delete.

  1. Restart your computer and check if the problem at hand got solved.

Note: The registry editor is a powerful tool. Changing keys which you have no knowledge about can damage your computer and even render it unusable. Proceed with caution. It is always wise to back up your registry before you make any changes.

Solution 2: Reinstalling Logitech Device Drivers

If all the above solution doesn’t prove any luck, we can try installing the default drivers for your mouse. Drivers are the main driving force for any hardware. They connect the device and give exclusive control of it to the operating system. We will uninstall the drivers and restart the computer. Upon the restart, the computer will install the default drivers back on your computer. If you get the checkbox “Delete the driver software for this device”, make sure to check if before proceeding so all the driver files are permanently deleted.

Note: If the default drivers for the device don’t suit you or are inducing problems, you can download the latest device drivers from Logitech’s website directly. After downloading the drivers to an accessible location, right-click on the device and click “Update”. You should choose to update manually and navigate to the driver you downloaded.

  1. Press Windows + R, type “devmgmt.msc” in the dialogue box and press Enter.
  2. Expand the category of “Mice and other pointing devices”. Locate the mouse, right-click it and select “Uninstall”.

  1. Now restart your computer. Upon the restart, it will automatically detect the Logitech hardware and install the default drivers into it.

Note: If you have additional Logitech hardware installed on your computer, you should try disabling it as well. Type “appwiz.cpl” in the Run window and a window will pop up where all the programs installed on your computer will be listed. Locate the Logitech software, right-click it and select “Uninstall”.
