By my System folder do you mean C:\Windows\System32? I tried that and a dialog box said that "the folder already contains a file with that name. Did I want to replace it?" Frankly, I'm worried about messing up my computer by doing something I don't understand. If the file's already there why can't I regsvr it? Or find it? And if it's not already there why did that dialog box say it was? Also, according to Properties this is an ActiveX Control file and I've heard that ActiveX controls can be dangerous to fool around with if you don't really understand what you're doing. Which I don't. Maybe I'd better just do without AboutBuster rather than get into really deep water. Can you clarify all this for me, or should I just forget the whole thing?
