Oh seems I found a fix for myself. seems the vivoxsdk.dll file in the installation folder had different security settings then the other files. So after the install was complete I took ownership of the pso_bin folder and made sure I also checked all underlaying files and folders. Then the same with the other settings.
Think I also saw this in another topic being mentioned, but when I first tried it, it was not working. I will try to find the link to that post and come back here.
