start-Process doesn't work for executable with dll's

[Patrick9999]

Product, version and build: Powershell Studio 2019
32 or 64 bit version of product: 64bit version 5.6.167.0 with update 1.1.33.0
Operating system: windows 10 Enterprise
32 or 64 bit OS: 64 bit

*** Please add details and screenshots as needed below. ***
I would like to run this exectable Process1.exe with next content
Start-Process -filePath "C:\Users\temp\MonInterface.exe"

the Process1.exe starts but Moninterface.exe is not started, but no errors seen.

MonInterface.exe script starts and works fine in correct folder C:\Users\temp\
can we upload .dll somewhere in Powershell studio?

Moninterface.ps1 script:

I am not sure what you mean by "can we upload .dll somewhere in Powershell studio?"

If your application has dependencies, like a dll for example, you should consider making an MSI for distribution. There you would add the dll and any other needed files.
Keep in mind that Start-Process is not a PowerShell Studio thing, it is a Microsoft PowerShell Cmdlet, which more or less uses the CreateProcess API call.
I am not sure why you would run an application from a users temp folder either, so I am guessing there is a lot of information on this you didn't mention yet.
