I posted earlier today regarding a missing driver error, but omitted to say that it was actually a RUNDLL error.

I've seen various websites and YouTube videos that deal with this problem, but many of the solutions involve downloading third-party software. Others involve reinstalling programmes or fiddling with the registry. I'd be happy to edit the registry entry or reinstall the program, but in this particular case the actual program where the module was/is located is not specified in the address.

In your opinion, which is the best way to get rid of the annoying error message that appears whenever I start up my PC?
