Rhino 6 Evaluation Install Unworkably Slow

I have a Windows 10 i7 2.4GHz 4 GB Ram machine.
Rhino 6 bogs down for 30 seconds on any operation, e.g. clicking the main menu.
Is this normal?

welcome Jonathan,


but…. 4gb ram???

I replied to the message to tech support.

All better now. Thanks for the great support!!! I removed the license and re-installed on a machine with 16GB ram.
