We have a user base of 500+ installs, including many Vista PC’s. What is important is that you have the official Vista Service Packs installed. We have not noticed any problems with a clean Window system with SP 1 installed. If you have some problems with the installation, make sure to let us know which exact Windows System you have (to find out, either press Win+Pause, or do Start | Run then enter “cmd” and you will see the exact windows version number which is on your computer, for example for Vista SP1 you will see Microsoft Windows [version 6.0.6001]). Tell us also in as much detail as possible what else is not working. Normally, if the installer starts, and you let it run fully to the end without stopping it half way, the program should install just fine.
