Had a problem with the new installer.
FIY this on Windows 7.
I just downloaded and installed in Win-7 64bit without problem. I haven't tried 32-bit which might be the issue. I have just changed to a win-7 64-bit machine for building (a 32-bit target) so there might be a change I missed. Can you confirm your system type?
If win-7 64-bit please try downloading again (if not already done) in case there was something wrong with the download.
That might be it. I am on Win-7 32bit.
