Currently reloaded C3D 2013. Did this very thing 3 times while creating a new profile each time. This is not working per these instructions.
Is there a different idea? I had this problem early with C3D 2013 and it resolved itself, most likely after an SP upgrade. I've now loaded all the latest SP and Hotfix files offered. Everytime the program is closed, the profile closes all the toolbars that were opened before shut down and the newly created *.arg file needs to be reloaded.
This drives me crazy and makes me go: ARGH!
Hoping there's help out there. Thank you.
This problem occurred for me after uninstalling and reinstalling 2015 C3D (and then installing SP3). First time I've seen this issue. I ran a repair (had to unistall .NET 4.6 and install 4.5) and now C3D is saving workspace settings.
