“LoadLibrary failed with error 87: The parameter is incorrect.” error occurs

When using Controller Tester, sometimes a warning window like “LoadLibrary failed with error 87: The parameter is incorrect.” appears.

This error occurs when there is a problem with the graphics card driver installed on the PC, or there is a conflict between the graphics card of the host PC and the remote PC when using remote access.
You can try the following methods to solve the problem.

• Update your graphics card driver to the latest version.
• If the current driver is up to date, revert to the previous version.
• If more than one graphics card is turned on, disable the graphics card in problem.
• If using remote access, disable the graphics card of the host PC and try remote access.
• Completely uninstall Controller Tester and reinstall.
