.exe is not a valid Win32 application

When you launch an executable file, Windows displays a message like:

Application name is not a valid Win32 application 

To remedy this, there are several solutions corresponding to different causes:

• File download
• IDE Controller badly configured
• Support CD / DVD unreadable
• File system corrupted
• File unregistered
• Virus / spyware
• Problem with browser configuration

Downloaded File

If the application in question was uploaded to the Internet, it is possible that it was corrupted during download. In that case just download the file again.

IDE controller badly configured

• Right click on My Computer and select "Properties."
• In the System Properties, select the Hardware tab then Device Manager
• Double-click the IDE ATA / ATAPI controllers
• Double-click on Primary IDE Channel and Secondary IDE channel.
• In the tab "Advanced Settings, under the Device 0, ensure that the command is set to DMA if available and not PIO only.

CD/DVD is unreadable

If the error is caused by a defective media, it is possible:

• Trying to read the CD / DVD in another drive
• To clean with a soft cloth and water (no soap)
• Attempt to retrieve the data with software such as WinISO free version, which will retrieve the damaged file.

File system corrupt

To check the integrity of protected system files, run the following command:

sfc/scannow

File unregistered

If the error occurs at the opening of files, click Start / Run, then enter and confirm the following command:

regsvr32 / i SHELL32.DLL

Virus/spyware

The problem is most likely a Bagle Infection.
