Install Money with the appropriate link from the what is currently the second post in this forum. Then if you install Plus, add the patch from the first post in this forum.
I hope the file you refer to is money.mbf rather than .bak. If not, search the old computer for *.mbf files.
1. On the old computer, close Money.
2. copy your latest *.mny file or *.mbf to your flash drive.
Open Windows Explorer (WindowsKey+E is one way to do that)
Click Tools->FolderOptions->View and un-tick (remove check mark on)
the HideExtensionForKnownFileTypes. Click OK. That way you will
be able to see the actual .mny part of the filename.
5. Move the USB flash drive to the new computer. Copy your *.mny or *.mbf
file to your Documents folder on the new computer..
6. Right-click the copied file in the Documents folder, and choose Open.
That should launch Money.
7. Once inside, Tools->Settings->BackupSettings to set the backups to a
place that exists on the new computer. Use Browse to help find a
place that exists. Consider your backup strategy. You may want to
make the upon-exit backup to be a place in your Documents folder,
and put your scheduled backup on a Flash drive. That way, a hard
drive crash does not make you lose all of your backups.
