I have VISTA too and had the same problem. You need to do this. 1. Find the shortcut for LEARSCAPE client, either on your DESKTOP or in All Programs.
2. RIGHT-CLICK on the LEARSCAPE client shortcut and select "Properties" from the menu.
3. Select the "Compatibility" tab
4. Check the "Run this program as an Administrator" box.
5. Click "Apply" then "OK"
You should now be able to run the LEARSCAPE client without a problem. It has something to do with the UAC control that exists in VISTA, which does not allow One Program to access another Program. Like the LEARSCAPE client using JAVA to run. I should actually make a GUIDE for VISTA since more and more people will start using it.
Any more problems, just contact me!!!
