Hi,

As I thought you have already tried a number of options. That wasn't obvious from your original post. In the programming world a 'hack' is also used to refer to a solution that is less than option (or non-standard) but nevertheless does the job. It's a term used to describe a solution that works but would not be recommended which I think is apt to describe what you've done. I'm sorry if I gave the impression you were doing something wrong.... Out of curiosity what is the main driver for rolling out Windows 7? Presumably all the interested parties have a previous version of Windows which can run IE7 and your application. As an aside Windows XP was a very successful OS in my opinion and lot of people prefer it to something like Vista...
