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.
Not all .dll errors stem from missing files. They can also result from version mismatches, file corruption, or software incompatibility.
