I apologize if this issue has already been addressed but I just installed DS 2015 (free version) and am getting this dialog box when I try to start the program...

I'm running Windows Vista Business (x32) with the latest service pack. Thinking that the install might have failed somewhere, I re-ran the SD install after each installation.  BTW, Windows is completely up to date with the latest drivers.

If this issue can be resolved I plan to upgrade to Pro. If not, I'll have to find an alternative. Any help would be appreciated.
