PSA: I don't know about other anti-viruses, but mine (Avast) detects the EXE as a virus. It's not. I had to add an exception to stop it from deleting the game.
Apparently this is a common thing with unsigned games made in Clickteam programs unfortunately.

Ran into the same problem myself. I unzipped the game several times and kept wondering why it "wasn't extracting" the EXE itself, and when I consulted my AV, it turned out it'd quarantined the file. But I restored the EXE and the game worked perfectly afterwards.
Oddly enough, it didn't happen with the original non-HD version.
