Stuck at "Checking System..."

[rste11]

I have an Officejet 4500 G510n-z. Downloaded the driver online from here:

I'm running the installation. First it extracted files into a temp folder on the C drive, and then it started installing. And it's stuck at the "Checking system" step.

What should I do?

Of course I don't want this thread to end up being one of those unanswered things that people find and never know what happened. So here is the solution, found weeks later:
