HomeTroubleshootingAll Products: Startup"Automation error: %1 is not a valid Win32 application"

2.25. "Automation error: %1 is not a valid Win32 application"

Applies to:
All products

Problem:
I try to start @RISK or another product, and I get the above error message.

Response:
Check in the root folder of your C: drive for a zero-byte file called Program. (You may need to change Explorer options so that you can view hidden files and folders.) If you find that file, delete it.

If the file doesn't exist, or if deleting it doesn't cure the problem, you may have a problem with the path of a service in Windows. For the problem description and solution, please see Event ID 7000 and "%1 Is Not a Valid Win32 Application" Error Message When You Start a Service in Microsoft's Knowledge Base (accessed 2012-11-09).
