Windows 7 64bit SP2 here. Just installed Cubase pro 10 upgrade from 9.5 Pro. My version is 10.0.20 build 187
For continuity, 9.5 is still there available at my desktop icon, alongside 10.
My Waves plugin license is on an external hard drive: by chance it was not connected to the PC when I launched Cubase: Cubase hangs 10 while scanning VSTs. The bug is repeatable sistematically. I need to stop Cubase from Windows.
Cubase 9.5 handles the situation fine: while scanning, a pop up window warns me that waves license is missing, suggests me to run “waves central” (the waves plugin license manager) and anyway decide if skipping or continue searching. I skipped and it launched normally. This is an expected logical behaviour.
In Cubase 10, the plugin licence missing window simply does not show. As a consequence, Cubase hangs on start up.
When I connect the external usb hard disk (containing the waves license) before launching Cubase 10, it launches fine.
