I got this problem with windows 10 on my new laptop. I wasn't able to install the wrong version, but the right one keeps crashing with this message, every time I tried, sometimes after 5 minutes, sometimes after 50 minutes.
I experienced and I found this solution for "my" caw: start caw with right click and "start as administrator". If you haven't the option to start as administrator, you have to activate the administration account for windows, run windows with administration account,, start caw, change to your normal windows account, deactivate administration account and now you should have the option, when you take a right click at caw. When I start my caw as administrator, it doesn't crash.
