Hi, I am running a 27" IMAC 3.4Ghz i7 using OS x 10.8.5 with Desktop 7 and OS x Server 10.5.8 as guest. The Tools installer runs fine, goes to restart, restarts fine, but Tools still is not installed. I have to use Desktop 7 because it is the most recent version that supports Server 10.5.8. I have Desktop 8 & 9 but they don't support 10.5.8 which I have to have for an estimating program. Any suggestions as to what I can try?
