Installed as Upgrade from Cubase 7.5. All successful and Activation done. When launched I get following error message
"DWM Composition is not running. Please switch to Aero theme.
Please help to resolve, can’t wait to explore new features.
Right-click on desktop, click Personalize. Choose one of the Aero themes.
Thanks ferro4prez for your help.
I logged in to write a solution told me by a local dealer, who rang me and resolved it , basically simple fix for Windows 7, use Aero theme. Thanks to Harold from Yamaha Australia.
Thanks to both of you.
The Desktop Window Manager (DWM) service must be enabled in order for Aero to function.
