Ok, I have the EXACT same problem that https://forums.sinsofasolarempire.com/307544 has. Fired up VMware Workstation, installed vista 32 bit and moved the saves over and works fine.
I am even running RC x64 too. However, I cannot find any posts about Win7 compatibility. Is this issue fixed in the release? To upgrade to release I have to uninstall RC and thats just going to be a pain, so I want to know whether I NEED to do it or, if its not compatible, to just wing it with VMware.
I backed up the error application logs and all the relevant files in the App temp folder. But no dump files were created straight to desktop.
