Change Product Key Of Mac Office 2008


Chances are, you may want to change the product key of your Mac Office 2008 upon finishing an update from their site because the product key used to install your Office 2008 installation used an invalid product key. If after the update it does detect that an invalid product key was used, the office assistant will keep on popping up while the application that you chose to open will never be seen. To reset the product key, delete the following files and send to trash.

  • /Users/[username]/Library/Preferences/Microsoft/Office 2008/Microsoft Office 2008 settings.plist
  • /Applications/Microsoft Office 2008/Office/OfficePID.plist

[username] would be the username of your laptop. Run any Mac Office 2008 application and the office assistant will now have a textfield of the product key for you to input.

    I had a similar problem installing Office Mac 2008 for the first time. During the installation I was not asked for a product key, and later it would not launch, but just stopped after running the customer experience and updates sections of the installation manager.

    The solution was:
    1: trash the OfficePID.list file from Applications/Microsoft Office 2008/OfficePID.list

    2. trash the folder “Office 2008″ from [username]/Library/Preferences/Microsoft/Office 2008

    After that, running any application brought up the product key entry window normally. The installation manager asked for customer experience entry and updates timing one final time. Then, after closing installation manager and re-opening the application it worked fine, as did the others.

    Thanks to microsoft tech support.

    Thank you…thank you…and thank you again.
    Of course the MS support site was useless and Mactopia forums and blog sites were not working. Sure they had the pages where you could buy more crap working….but if you were a customer that needed support…oh well. Typical Microsoft.
    Thank you so much for this. Worked perfectly.

  37. 37
    tech Says:

    @Jodi: go menu is under finder. :) if you still are having a hard time, use the short cut

    SHIFT + APPLE + G

    make sure the finder icon has the focus.

    I did all this and everything is all well and good—except now I don’t know what product key to use or where to find it. I downloaded the software online, and there were product keys in my confirmation email, but now I am not sure how to return to the email. What do I do?

    Adrian got it right above. Just deleting the OfficePID.list file didnt work. I had to delete the preferences folder as well.

    The solution was:
    1: trash the OfficePID.list file from Applications/Microsoft Office 2008/OfficePID.list
    2. trash the folder “Office 2008″ from [username]/Library/Preferences/Microsoft/Office 2008

    This will help in imaging… we can install 2008 on a machine to be cloned to many machines and then do this trick to enter a new code. Much better than having to install office a number of times. Cool!

    perhaps your key is not recognized by microsoft office to begin with

    lazarts Says:

    The whole thing with getting it to work with this link that’s supposed to provide you with working keys is just crap! Do what I did: uninstall Microsoft Office 2008 for mac, reinstall it and NEVER do an update again. Works fine for me since then!

    Arif Says:

    Tammy Says:

    Same problem as gins. Removed those two files just fine. The box comes up to activate what I opened, Word, and when I put the key in, it says in red text you’ve entered an invalid product key please try again. It also says my 30-day trial version has expired. But I searched for the trial version just in case and it’s called Test, which isn’t on my computer anymore.

    I tried the manual activation with the product key and it says call cust service for the activation code. That pages takes you to another page that you have to fill out and THEN it says they’ll get back to you in 2 biz days. Does anyone know any other way to contact customer service to get a real person in order to get the lousy activation code? First mac, I’ve never been so frustrated. Ever.

  66. 66
    Tammy Says:

    Gins, I hope you’re reading! I just spoke with a microsoft tech rep, 800-936-5700, and she was the best. Did you have the 30-day trial version first by any chance? I did, and that was the problem. Yes, I searched for it with the Remove Office tool, but it doesn’t always find it apparently, and some components remain, interfering with the components of the full version. If you have a blue folder called Microsoft under Go, Home, Library, Preferences, it needs to be put in the trash. (It has confused registration components in it). Empty trash. Restart. If a Microsoft Office 2008 folder is still in the trash, empty the trash. Next, trash the W, X, P, E, messenger, and doc collection icons on the bottom. Empty the trash. Reinstall MS Office from the disc. Check for updates and first install 12.2.3, then it’ll auto check for updates again. Install 12.2.4. It should be good to go. -Tammy

    did you try deleting the plist files?

  76. 76
    Jamie Says:

    Ok, I still can’t get this to work.

    I deleted the plist, but apparently don’t have the other file that I need to delete. Is there anything else I can do to reset the key? I have a new product key to use, and when I enter it in with just the plist deleted nothing happens, although I don’t get an error message, which is promising.

    Anywho, this is really helpful, I just need to know if there’s anything to do when I don’t have that other file to delete.

  77. 77
    tech Says:

    as far as i know, those are the only files that you need to delete

    it worked for me

    I have the same problem a lot of other people have been mentioning; that after I delete the files and start up the setup assistant, nothing happens when I paste the key and click continue. It’s pretty frustrating.
    Any ideas? Help would really be much appreciated. Thanks guys.
