EasyBCD 2.3.exe won't run

Hi. I'm trying to install easybcd on a Vista machine, with .NET 2, 3, 3.5, and 4 all installed and verified (I just ran Microsofts .NET verification tool.

When I try to execute EasyBCD 2.3.exe to install the program, the mouse cursor briefly turns into a circle, then nothing else happens. No error messages, nothing. There are no easybcd programs running in Task Manager, nothing starting with bcd, or boot.

I've tried running it as administrator but that doesn't work either.

What could be wrong?

Thanks in advance.
