How to Fix an Invalid Win32 Application

By Kefa Olang

An invalid Win32 application error is usually caused by a number of factors such as a corrupt, bad or missing file within the application, the program is installed on an operating system it is not compatible with, or it is infected by a malicious parasite such as a Virus, Trojan, worm or malware. These errors cause programs or files not to launch properly. There are many simply ways to troubleshoot and solve invalid Win32 application errors.

Step 1

Launch your anti-virus program and perform a full-system scan to remove any malicious files that could be causing Win32 application errors. If you do not have an anti-virus program, download a free program such as AVG Anti-Virus (see "Additional Resources," below).

Step 2

Launch your program after it has installed, then click the "Update" button to install the latest virus and spyware definitions. Perform a full-system scan and delete all detected malicious files.

Step 3

Run Disk Defragmentor to fix file errors. Many times, Win32 application errors can be caused when program files are scattered on your computer. When files are scattered, the programs that use them have slow launch speeds and occasionally freeze. Disk defragmenter helps put the files back to a central location. To defragment your hard disk, click the Windows "Start" button and choose "All Programs." Scroll up and select "Accessories." Select "System Tools" and then click "Disk Defragmenter."

Step 4

Click your hard drive under "Volume" to highlight it and choose "Defragment." The process may take a couple of hours depending on your computer use.

Step 5

Uninstall and reinstall a program if it has become corrupt. To uninstall the program, click the Windows "Start" button and choose "Control Panel." Double-click "Add or Remove Programs" to open programs window.

Step 6

Locate the program that is corrupt and click "Remove/Uninstall" to uninstall it from your computer. Insert your installation disk into the CD-ROM drive to reinstall the program. If you originally installed the program from a website, navigate to the website and click "Download" to reinstall the program.

Step 7

Check for compatibility before downloading certain programs. If the program you are attempting to download requires more RAM or processing speed than your computer offers, it may be best not to download it.
