Powershell script runs fine on one computer but errors out on another

Question

I wrote a PowerShell script that calls a C# exe file that works no problem on my machine and a couple other machines on our network, but for some reason it won't run on the computer it needs to. This is the error I get when I try and run it. Any ideas on what could be causing this?

Start-Process : This command cannot be executed due to the error: %1 is not a valid Win32 application.

It will run no problem on a couple other machines on the same network no problem, just not on this particular one. Any input would be helpful, thank you!

Your C# application was built for Win64 and you're trying to run it on a Win32 version of the OS. 64-bit applications cannot run on a 32-bit OS. — Ken White

Gotcha. So for it to work on that machine I'm gonna have to write a new version of the C# program? — Mitch

No. Compile the same C# program with AnyCPU as the target (or compile it as 32-bit, which will work on both 32 and 64 bit versions of the OS). — Ken White

I am running this in Visual Studio, how would I do that in there? or do I have to do it through command prompt? — Mitch

It sounds like your C# application was compiled as 64-bit, and you're trying to run it on a system with Windows 32-bit. 64-bit applications will not run on 32-bit operating systems.

Rebuild the C# application with either AnyCPU or Win32 as the target platform. You can do this through the Project menu; edit the properties of your application, go to the Build page, and change the Platform in the drop-down list at the top of that page, and then build your project.

Can't be sure, but I think your app is 64bit compiled, and you're trying to run it on a 32bit machine.
