A Microsoft Passport was (and still is if it was not removed) a combination of email address and password. It was replaced by Microsoft’s Windows Live ID.
A Microsoft Passport cannot now be removed from your file because the online server that would need to authenticate the removal no longer exists. You will need to remember the email and password combination to access the Money data file on your new computer.
Your Money 2005 CD will not install an up-to-date version of Money 2005. You need the appropriate regional QFE2 installation file. See Download Microsoft Money Installation Files: Solve Activation and Some Other Errors . If you are not in the USA or Canada, Money Sunset cannot read your data file.
If you still have your old computer, you can export and transfer your data with the qif import/export procedure. Consider transferring your data to a newer, actively maintained program if you choose this method.
