Can confirm it’s a virus, but like, not a virus virus, it’s just an broken AF 7zip extractor that doesn’t close until you restart your computer, I had no issues following download and extraction after restarting
Sorry about the trouble. It is indeed a self-extracting 7zip file. Some virus scanners report it as a false positive but there are definitely no viruses are in it. To make things easier, we've made a simple RAR version you can download instead.
FYI, game don’t run unless you have 16GB of RAM available
