Copy your main *.mny file and recent *.mbf files to a USB flash drive or other media. Remember that drive will contain confidential info, so act accordingly. Copy those files to your Documents folder on the new computer. You could alternatively copy to a
sub-folder in Documents or elsewhere. Just don't put your *.mny or *.mbf within a folder that is within either the ProgramFiles or Windows folder.
Install Money 2004 on the new computer with your install disk. If you don't have that, and if your Money is a US version, install Sunset. (If you don't have an installation disk and your Money 2004 is not a US version, that is a problem.) Start the
new installation. Open your *.mny file.
In Tools->Settings->BackupSettings for Money Plus Sunset or Tools->Options->BackupSettings for Money 2004, change the location to which Money backs up to a location that exists on the new computer -- typically your Documents folder or a
sub-folder in Documents.
