myapplication.exe is not a valid win32 application.
I have research on it and found some reason as it is below

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

What happens if you recompile it? You cannot say for sure it's not a virus, as it could be infected at any moment of time.
