Microsoft Windows XP: Broken File Associations

Symptoms When loading a file, you must select a program for it to be loaded with
   
Cause File association is broken
   
Resolution The files listed here are all ZIP files, which contain a REG (Registry) file. Download the ZIP and open it. Extract the REG file to your hard disk and double click it. Answer yes to the import prompt. REG files can be viewed in Notepad. Each of the REG files contains the default settings for the file extension indicated. For the ZIP file fix, the download is a REG file, since ZIP’s aren’t working anyway!

NOTE: If your EXE file associations are corrupted, it can be difficult to open REGEDIT, or to even import REG files. To work around this, press CTRL-ALT-DEL and open Task Manager. Once there, click File, then hold down the CTRL key and click New Task (Run). This will open a Command Prompt window. Enter REGEDIT.EXE and press Enter.
