Goals and Symptoms

On some PCs, the simulator of Unity Pro V5 or V6.0 doesn't run, because in the Appearance settings, Window Aero as Color scheme is selected.

Causes and Fixes

Replacing Windows Aero by Windows Basic (Standard or Classic) fixes this issue.
How to change the Color Scheme:
- Right-click on your desktop, then click Personalize. (Or, from the Start menu, select Control Panel and click Appearance and Personalization)
- Click Window Color and Appearance
- If Windows Aero is already selected, click Open classic appearance properties for more color options, then in Color scheme select Windows Basic, Standard or Classic
