Error 193: %1 is not a valid Win32 application
Posted on Nov 26, 2007 under Windows Tips |You get an error when starting a Windows Service:
Error 193: %1 is not a valid Win32 application
This could be caused by a folder on your hard drive that has a similar name to the folder that contains the path to the service. For example, if the path of the executable file for a service is C:\Program Files\ProgramName\ServiceName.exe, and if a folder that is named C:\Program also exists on your hard disk, Windows locates the C:\Program folder on your hard disk before the C:\Program Files\ProgramName\ServiceName.exe file, and then tries to run it.
You can get rid of the Program folder, or perform the following steps:
1. Click Start > Run and type REGEDIT and click OK.
2. Click the plus sign next to HKEY_LOCAL_MACHINE
then SYSTEM
then CurrentControlSet
then Services
then ServiceName
3. Right-click ImagePath on the right side. In the Value data box, place quotes in the path.
Example:
Change: C:\Program Files\ProgramName\ServiceName.exe
To: “C:\Program Files\ProgramName\ServiceName.exe”
4. Click OK and close REGEDIT. Restart the computer.

It sounds like the software you downloaded is corrupted. I would try downloading it again.

I have the same problem with Vista. New HP Pavilion. Hard drive failure. Best buy replaced and reinstalled OS and returned. Now have flash error and can’t open PDF files. Error %1 not a valid Win32 application. Also do not have “ServiceName” to do above repair. Any help because Best Buy is useless once paid.
