EVK1 VGA is not seen by metavision studio 3.1

EVK1 VGA is not seen by metavision studio 3.1

I have EVK1 VGA camera, one of the old ones, I also installed metaviison_sdk 3.1 beucase it is latest version that supports that cameras, but when I click open camera i get only "No Prophesee cameras available, please check that a camera is connected to the server." problem. I installed metavision studio and sdk 3.1 on windows, and it worked, so the problem should not be the hardware or something related. Can you suggest solutions? Is there some steps to setup plugins etc, because i did not find such instruction on the website, also in FAQ section
