We can successfully install the GP client. The problem comes in when we launch the GP client for the first time.
It has to synchronize a file call DYNAMICS.DIC to what it finds on the server.
This file is located in C:\Program Files (x86)\Microsoft Dynamics\GP2018
For whatever reason something is blocking it from updating that file. I have never seen such behavior in the 25+ years I have been installing GP.
The one difference is Parallels and the few times I have run into this on the GP Forum there are always problems. In my opinion there is some permission issue.
Do you think installing GP into some other folder outside of C:\Program Files (x86) may help?
Personally I would dump Parallels but that may not be an option.
