Avi file extention corrupt after using CCleaner registry cleaner

[nukesgoboom]

Suddenly and without warning, my .avi file extentions in windows xp have become broken. I think this was related to CCleaner's registry cleaning.

 

I tried going to Tools->Folder Options->File Types and i found that the .avi file extention doesn't exist. I tried to add it by clicking New... and typing in AVI. it stays on the menu until i close it, and when i reopen the File Types menu, there is no more AVI extention! What is going on here? Is there anyway to make the AVI extention permanent in the File Types menu? I also cannot change the icon which sucks, it defaults to the windows media player icon.

 

Why is this happening? If it was really just a registry cleaning problem, why can't i recreate the .avi file extention? I can open .avi files on double click only during that session of windows, but i still cant change the icon at all!

 

 

Thanks for your help!

CCleaner will make registry backups if you tell it to, so if you have the one from when the avi extension was removed that should put it back.

greetings friends. i was able to fix my problem with a little twist on the normal way of doing things.

 

i want to tools, folder options, then file types.

 

i clicked new, and for the file extention name i typed avi

 

this had all been tried before and failed, but here is what i did differently. i clicked on Advanced and then in associated file type, i scrolled down to avi which existed akwardly, just the way i typed it in all lower case letters while the other extentions were uppercase or dramatically spelled out.

 

i hit OK and changed the icon back to what i wanted it to be, then restarted my computer.

 

success, the files now carry the icon i wanted and they open on double click after a restart.
