Just thought I'd update this thread with tips for people having issues w/ AUTORUN.INF errors when attempting to install the copy of Money from the archive.org page.
You'll need to first extract the files by entering this command (I do this from the command prompt):
USMoneyDlxSunset.exe /t:c:\msmoney /c
This will create a new folder on your C: drive called "msmoney."
Now, from that folder, you want to run "mnyinst.exe" to start the installation. You may need to right-click it and "run as Administrator" (I can't recall if I needed to do that or not). You'll get a warning that you should run setup.exe instead, but don't. Just proceed with mnyinst.exe and it should install.
Hopefully that helps someone.
