The Grand 3 on Windows 7 64

Hi guys, Im now wanting to install The Grand 64 on Windows 7. I’ve uninstalled the 32 version.
The trouble is i can’t get the installer to start, Ive gone in to the application and changed the permission to administrator. And changed the compatibility to run on windows XP service pack 2. And it wont start! Help.

im having this same issue, WHY is it that it’s gone on for 2 or so years without ANY response from the support team… I paid 250 for the grand 3 off sweetwater 6 months ago and now all of a sudden it’s giving me massive problems and I can’t update to the newer version, AT ALL.
