No g-code file generated by Madcam in Rhino

I have encountered a problem that I am unable to resolve.
I have attached a picture, which shows on the right the window for postprocessing and creating g-code file. No errors there and it says the location and name of the file that was created.
But the problem is that the file is not there. In the attached picture on the left is "open" window at the folder, where the g-code file should be, but the folder is empty.

I have tried reinstalling Rhino and Madcam and now I am totally out of ideas.
I would appreciate any suggestion or poke in the right direction. Thanks in advance!

Can you make a test with the default 3 axis LinuxCNC post processor?
I have a feeling that the post processor might cause an error and the error is silently thrown by the generator.

Try sending it to desktop

thanks for the suggestions! I already had tried different other postprocessors (for Mach3 etc) and also tried different output folders, but it was still the same.
but I made progress, when I reinstalled windows... no idea, what was the cause

It was Windows then! :D
