  • Try either of below ways

    1. Build your project in x86 mode. You can do it in project properties.

    OR

    2. I think "excuteFile" application uses native 32 bit instructions. So, build "excuteFile" using x86 configuration.


    Please mark this post as answer if it solved your problem. Happy Programming!

  • What if you specify the full path to excuteFile.exe, and double check that it exists on disk first?
