In case anybody has been trying to get Money Plus to run, I think I found the key! Finally, a great personal finance app running on the Mac (Snow Leopard 10.6.4) without having to install Windows!
I was able to install the latest edition of Microsoft Money Plus and it works fantastic! I had previously been running it in Windows 7 on Parallels Desktop 6 on a 2.53 Ghz Intel Core 2 Duo MacBook Pro with 4 GB RAM (worked well, but was still way slower than running CrossOver).
First, I installed CrossOver for Mac. Next, I installed Money Plus - the 'Sunset' Version http://www.microsoft.com/money/sunset.mspx in a Windows XP bottle. Lastly, I installed Internet Explorer 7 in the same bottle (without it, you will get an error when attempting to open Money).
So far, it has been working perfectly!
