In some cases, you may need to register the .dll file. To register the .dll file, open Command Prompt as an administrator, enter the installation folder, and run the "regsvr32" command. You'll receive a confirmation if the .dll file is successfully registered.
Unregistering a DLL file deletes its information from the Windows registry. Keep in mind some DLL files can't be unregistered.
For addressing multiple .dll issues, the System File Checker tool, utilizing the "sfc /scannow" command, can help rectify system-related .dll problems.
