You would need to back up the Money file first.
Then uninstall Money . Through add remove programs if its windows xp.
Then go to : https://www.findmyorder.com
Sign in with your information.
If you have any qwestions regarding the download call : Microsoft Online
Store Phone: 952-646-5047
Download the Money Plus Deluxe to your computer. I would suggest saving
the file to the desktop for the time being.
Then you can burn it to a cd or save the file to a memory stick.
Run the file from the desk top. Open Money , then you will be promted
for the activation key.
The artcile have more steps to help install the program

Hope this helps

I purchased MS Money Plus Deluxe and downloaded the trial version. I have the
confirmation email and also the activation key. The instructions say to open
Money and then click on Tools | Online Services Information | Activate (and
enter #). However, "Activate" is not there. It tells me I have the trial
version, but either I can purchase it (I already have) or use the product.
How do I activate this?
