Badbru, thanks for your step by step procedure. I'll try it with BSN 1.8. Here's a couple of quick comments.
FYI if you decide to do BSM 1.8. I purchased 7.62 from GamersGate in mid-2010. 7.62, Brigade E5 and other games, are now in "My Games" folder permanently. I can download them as many times as I wish. I would think you can do that too but there's a reason you can't? Anyway,
After I d/l & install 7.62 from GG, I get a window that asks me if I want to delete the temp file, save the temp file for possible reinstallation, or restart the installer. I finally started saving the temp file and don't have to d/l each time I want to install 7.62 after I screw things up.
I haven't come across the mscvr.117 issue yet so I'll look that up later, unless you have a link to that thread.
Thanks again, OneMug
