Playing the demo of Victoria 2 did not turn out well. I got through one tutorial and then the demo crashed.
So, I'm not going to debug a demo, no not today thank you. Tried to delete demo via Control Panel. Appeared to work, but did not. Reboot, tried to delete Demo using the supplied utility. This did not work either. Sigh. Plan B. Remove all files manually. Run CCleaner. Use Registry tool. Search through registry with RegEdit to make sure. Reboot. Check the usual ratholes where programs leave "Easter Eggs." Think I got everything.
Victoria 2 looks really good. I'm impressed! I'll keep up with the forums and let it get patched a few times.
