2. Uninstall the program that is crashing. It is possible to fix the program's corrupted files while the program is still installed, but to make sure that you clear the program files completely, it is safest to completely uninstall it from the system.
3. Run a full scan of your computer. Your computer should already have antivirus software installed that can scan for corrupted files and either fix them or delete them from your system. If you do not have antivirus software on your computer, that could be a big part of the problem. Purchase and install antivirus software as soon as possible. These are designed to protect your computer from outside threats. Once you have the antivirus program installed, open it and click "Scan Computer." The antivirus scan will isolate bad files and you will be given the option to remove them from your system.
4. Reinstall the program that was crashing. Now that the corrupted files have all been removed, your program should run smoothly after re installation.
5. Check for program incompatibility. If, after a thorough scan and cleaning of your computer and re installation of your program, the Appcrash errors continue, the program you are trying to use may not be compatible with your operating system. For instance, there are some DVD software's, such as Media Now, that do not work correctly with Windows Vista. These lists can be easily found online. If this is the case, you will have to purchase a software program that is compatible with your operating system.Another problem that occurs from time to time is programs that are not able to be installed on the same computer at the same time because of program compatibility issues.
