Question Not a valid Win32 application

Not a valid Win32 application.

Often this error message will be similar to the below error message.

C:\Program Files\myprogram\program.exe is not a valid Win32 application.


This issue can be caused by any of the below possibilities.

  1. File is corrupt, bad, or missing.
  2. File is not designed for your version of Windows.
  3. File is a virus, worm, or other malware file.
  4. Hardware incompatibility.


File is corrupt, bad, or missing

If the file or program you’re attempting to run is corrupt or missing, Windows will be unable to execute the file properly and sometimes generate this error message.

Download files

If you downloaded this file and verified it is complete and compatible with your version of Windows, delete the file and try downloading and running it again. It’s possible during the download that the file became corrupted.

Finally, if the second download does not work, try downloading the file from a different webpage. It is possible that the person or company maintaining the website mistakenly uploaded a corrupt version of the file you’re attempting download.

Installing a program from a CD or other disk

If you’re attempting to install a program and are getting this error, verify that the CD is clean. If the CD is dirty or bad, you could get this error during the install or after the program has been installed because it was not copied properly onto the computer.

Running a program from the computer

If you’re running the program from a shortcut on the computer, verify that the program is still on the computer. In some cases if the program is no longer installed on the computer you may get this error.

If the hard disk drive is corrupted or bad it can also cause working programs to fail either because not all the data can be read from the hard disk drive or because the program has become corrupted while on the drive. Run scandisk and defrag on the hard disk drive to check for any potential errors.

Long file name issue

Make sure the program or file you’re attempting to run does not contain the same name as the long file name directory it is contained in. For example, executing a file named “program” in the “program files” directory can cause errors in some versions of Windows.

Additionally, if you’re attempting to install a program and after the install the program does not work, you may also want to try installing the program in a different directory.

Bad file

Any file can be changed or renamed to be a .exe file. If you’re downloading the file, make sure the file is supposed to be a .exe file and that it’s not being changed. If you’re attempting to create a .exe, file make sure you’re compiling the file for Windows and never just rename a file to a .exe file. For example, renaming a .bat file to a .exe file will not make the file an executable file. For a file to become an executable file it needs to either be compiled or converted through a software program designed to convert the file.

Windows XP has an auto logon feature, which can be very useful for a person who is the chief operator of a computer. A person not bothered by the trivialities of having to share his/her computer can easily employ Window XP’s auto logon feature. By using this simple auto logon feature, one can use a computer without the hassles of having to enter his/her, username/password combination. Firstly, click the “Start” button and select the option “Run”. Next, what appears is a box titled “Open”. In this, “Open” box, type the command “Regedit”. After having typed this command in the “Open” box click “Ok”. Next, navigate to the:

HKEY_LOCAL_ MACHINE\ SOFTWARE\ Microsoft\ WindowsNT\ CurrentVersion \Winlogon key
The string value “Default password” should be missing. This option should be turned-off. Next, open the registry editor menu and then click the “Edit” option from the registry editor menu. Then, select “New” and click the “String value”. There should be a box that must, by now be visible if every other step previously mentioned has been strictly followed. In this box there will be an instruction visible that says: New value #1
In this box, type the command “Default Password”. Now, after performing all these steps there should be a “Default Password” entry. Double click this entry. Next, enter the password for the user account that is required to be automatically logged-on. Next, click “Ok”. After, having performed all these steps there should be a string by the name of “Default Username”. This should contain the user account for which the user wants to automatically log on. Next, click the “AutoAdminLogon” and change its value to 1. Finally, click “Ok”. Now the user is instructed to close the registry editor.
