Just tried to install metamorphose2_0.6.5_setup.exe on Windows 7 x64. Could only do so after running the installer as admin.
Thanks for the report. I don't have access to win 7 yet so am unable to test. I did make some changes to the installer that should have allowed running as a regular user, obviously this has not worked.
I'll update this report when I have more info and experience with win 7's privilege escalation model.
App now asks for admin access.
