I am running Windows 8 Preview 64 Bit in Virtual Box on OSX Lion on an old MacBook Pro.
I did enable .Net 3.5, which is required by Mission Planner. When running the APM Mission Planner installer, it announces that an error has occurred and aborts the installation.
I realize that there could be all kinds of issues leading to this, and the Error is completely generic. But maybe someone here has come across this situation and solved it ?
