Hello,
When I install Dynamics GP 2018 using an installation package I created, I get a bunch of different file paths in my DYNAMICS.SET file.
The ones that don't have GP2018 don't work, because the folder "GP" doesn't exist. I've recreated the package a few times with all the defaults, and this is how it installs each time.
If I just run the setup.exe file, and use the defaults, everything is "GP" and works fine.
