I'm on Windows 7, and have had no problems at all.
However, you might need to download and install MSVBVM50.zip from the
files section. It seems hit-and-miss whether or not computers have it
these days.
(Instructions: Before installing, make a DMGenie folder and place this
file inside, then install DMG to that folder. The error warning comes
up, you open the file, drop it into the subdirectory, and VICTORY! )
