OK, so apparently lots of people are having difficulty with this since this application was not developed to run in a 64 bit environment.
So, the developers at Microsoft, in their infinite wisdom provided us with "Compatibility Mode."
Here is what I did to get this application to work in XP 64, should be the same for Vista.
1. Download the latest
Sprint Media Manager for Instinct. 2. After DL is complete, right click and select properties.
3. Compatibility tab, select "Run this program for: Windows XP"
4. Install
There, reboot and run!
