Run RealityCapture.exe in powershell

Just to clarify, what do you expect as log file?
How was code using -writeProgress written? The created file should look like this: RealityCapture Help
If you wish just to view the console view of the process, you can use it like this:
-stdConsole >> "C:\Documents\Testing\console_report.txt" ^

I am not aware of such usage. But it is possible to run it on virtual machines.
