Be sure that your Money and backup files
are moved to a spot that you will have full privileges to, such as
Documents. If they are within ProgramFiles, Windows 7 will
create an impermanent copy of the file for the user to use, unless
the user explicitly right-clicks at launch and chooses
RunAsAdministrator that time.
I presume your Money version is not from the US. Then if you did not do so before, it is critical that you make an installation disk using files from your old installation. That will give you the ability to install Money 2005 with version 14.0.*.1105.
