Running VirtualAcorn Products on Windows 7

Before installing any version of VirtualRPC on Windows 7 please read the whole of this article.

Windows User Account Control (UAC)

User Account Control (UAC) was introduced in Windows Vista. Under Vista UAC could only be turned on or off, under Windows 7 this has changed. Before you unlock a copy of VirtualRPC on Windows 7 you will need to change to Windows 7 User Account Control setting to Never Notify.

The User Account Control slider shown in the above example can be found from the Windows Control Panel. Having altered the UAC slider and clicked on the OK button you will be prompted to Restart your Computer. This restart must be performed before trying to unlock your VirtualAcorn installation. Having restarted your computer you can now unlock your VirtualAcorn installation in the normal way.

You must leave UAC at the Never Notify setting and must not alter it again unless you are not going to run any VirtualAcorn products on this machine again.
