Thread: Application issue in Vista

I have desktop computer with windows vista operating system. From last 2-3 days my computer is showing error as Application Not Found Error and similar error shows for various programs. When I try to Firefox open it gives same error and doesn’t proceed with it. Any help would be highly appreciated. Thanks in advanced.

If Mozilla is not default browser and try to run similar again. Also make sure that you are running application from shortcut. If yes then delete shortcut and restore it.

I think your allocation is damaged. Try to run System File Checker which detect System for damage installation and if found any then fix it. To run then System File Checker first open command prompts and type sfc/Scannow in it and hit enter.
