Windows Error: Invalid Win32 application



The Error: The error message, “________________ is not a valid Win32 application,” 


can occur when you try to open a program or file. This error message can be caused by a number of issues including a file designed for a different version of windows, a corrupt, bad, or missing file, or a mismatch of 64-bit program on a 32-bit Windows machine.


If the error message is in response to a downloaded file, confirm that the file is compatible with your version of Windows, then try deleting the file and re-downloading it in case the download process corrupted the file.

If the error occurs in response to opening a program, check that the program is installed on your computer (particularly if you’re clicking on a shortcut) and make sure the program does not contain the same name as the file name directory that contains the program. You might also try installing it in a different directory. Also install the latest drivers on the machine to help rule out hardware incompatibilities.

Lastly, if the issue is a mismatch of a 64-bit program on a 32-bit machine, then your best bet may be to install the 32-bit program instead.
