|I found a solution on majorgeeks.com. Use the link|
and then scroll down to no 12. Save to desktop and then RMC and merge. It
restores exe file associations.
If you go to the website Antryg links to, open number 12, firefox and chrome seem to just open it as text, so copy all the text and paste it into a notepad document. Then go to File, Save As. Under "Save as type:" select "All Files" and give it a name you wish with a ".reg" (without the quotes) extension after the name. I saved it to the desktop that I was working on. Then just double click it, if it gives you an "open with..." error, you might have to right click the file, and go to run as, then uncheck the box that says something like "protect my computer and files from programs" then click okay and run it. This will prompt you with a new window asking if you want to make the change to the registry, click "Yes" then restart your computer. It worked like a dream and fixed that issue as well as a few other minor ones. The only thing you have to be worried about is if the error was caused by a virus you removed, one or two of your programs may need reinstalled/repaired. This is what I ran into, but it was tax software that's not too common, so not much to fear.
