This beta appears to have solved the problem of blocking access to the other computer on my home LAN. Unfortunately though the GUI does not display. I can verify, via Process Explorer, that both DCSUserProt.exe and pgaccount.exe are loading. Examining the PG registry keys on both systems revealed something very interesting. On my desktop system that the beta is working on, there are 50 items in the PG key. while on the notebook only 5 items appear in the PG registry key. FWIW - I have made sure there is nothing running during the last PG install, there have been several including manual removals, that would block the registry keys being written. I may try to delete the PG key on the notebook and import the one from my desktop, just to see what happens. NOTE: I have sent DCS support an email outlining this problem, what I have found concerning the PG registry keys. I also included a Process Explorer file showing the PG/DCS files are loaded and running, as well as a zip file of both PG keys. Anyone here have any ideas as to what would cause this, or how it can be corrected?
