OP,
Never run an application you do not trust. The file isn't digitally signed &
if you try to run with restricted user rights then it fails because the
author hasn't done any code access permissions - poorly coded. I suppose any
Tom, Dick or Kelly can download the Express version of VS .NET (VB/C++/C#) &
code a poor application which in this case can lead to a corrupt registry
Besides, if it uses Kelly's registry settings from her own machine you
cannot be sure that the junk in those registry keys are good for your own
computer. Also, you can have different entries between SP2 & SP3 meaning you
could be setting the wrong value
Use it at your own risk
