Crystal Reports 2013 fails to install

I'm trying to install an evaluation copy of Crystal Reports 2013 on my Windows 7 64 bit workstation. I downloaded everything, unzipped it. When I double-click on the setup.exe file I get the user account control prompt, I answer OK. Then nothing happens. I've rebooted the computer, same.

I poked around some and found an old Visual Studio 2008 version of Crystal Reports. So I removed that, didn't make any difference. But maybe there's something left from that which is causing this problem.

I used to have VS2008 on this workstation, but now I'm running VS2013.

Any ideas on how to get Crystal Reports 2013 to install much appreciated.
