I'm having installation issues with Windows 8:
If you are using Windows 8 and you are experiencing installation or launch errors please try running RO2 in the Windows 7 compatability mode as seen here: http://www.dummies.com/how-to/content/how-to-run-older-programs-under-windows-8.html

If you are not using Windows 8 or are already running RO2 in Compatibility mode then please see this Knowledge Base Article:
