If you are thinking of selecting the options along the lines of "Do not update this ArchiCAD" until we get to the BIMServer, that is what we did to no luck.
However, this issue had been resolved the next day when our IT guy came in for his weekly tasks. He said the .exe file worked successfully when it was copied over onto the desktop of the 64-bit server Windows and then opened instead of opening from the shared network. I don't know if that made sense, and he did not know what was wrong since he did it right the first time around. Perhaps one of those things when the computer responds to the IT people than the users.
Thanks for responding, Link. This issue may have only concerned us but again, it's resolved and the BIM Server works great.
