I am running SW2011 on a x64 machine with windows 7 operationg system. When looking at a compatibility mode option I only have the option to run it in a Vista compatability mode. On a different x64 machine that is also running windows 7 I have the option to run SW in a windows 7 compatibility mode. What can I do to get the first setup to have the option to run it in a windows 7 compatibility mode?
