Hi Leo, I have a problem installing a program, it's called Magic the Gathering Online, the first window appears and I press the "install" button, but then crashes and tells me that needs to close, i don't know why, and a message tells me that the error has created a file "appcompat.txt" i don't know what that really means and the file has the next text:








I hope you can help me out. I don't know what to do.

I had the same problem with the "appcompat" message every time I right clicked on a file in explorer. After reading other articles on the web, I solved the problem by deleting the file, C:\Program Files\DivX\Dr.DivX\EncodeDivxExt.dll. This may not solve the problem for everyone, but it worked straight away for me. If you have Divx, this file is often the culprit.

I get this error starting up after browsing pr0n. The solution: Download your favorite porn so you don't have to visit the sites, then format C.

Haha!

Whenever I open a program such as Winamp and now Task Manager, it gets the appcompat.txt error. I'd enjoy your help.

If Windows XP I would start with the System File Checker: http://ask-leo.com/what_is_the_system_file_checker_and_how_do_i_run_it.html

I cannot type into the aim text box. It tells me there is an error occuring in appcompat.txt, with a different file name each time... I have removed and downloaded all available versions of aim and I still have the same problem.
What can I do to be able to type in AIM again?

I'd be tempted to check for spyware, and probably also run a system file check:
