Installation of serviio 1.5.2 crashes

I can't install 1.5.2, it just crashes. I've right-clicked the setup file, and removed the blocking, and runned it as admin, but still this crashes. Anyone had this problem?
I first tried to run this setup before uninstalling a rather old version, thinking the setup would figure out my older version and uninstall it for me, which might have fucked things up. Now I have none. Any advice?
