Reinstall Office 2010 on new laptop

Jenny S 0 Reputation points

I need help to re-install my Office 2010 Professional Plus onto my new laptop as I have dropped my old one and then had to migrate my old programs to my new laptop.

I have tried installing Office 2010 Professional Plus onto my new laptop but when the program asked for my Product Key, it says that it is not the correct one. I have the DVDs but my new computer does not have a DVD reader.

I spoke with Microsoft support & I was told to delete Office from my old computer which I did but I still cannot install on my new computer. I've made numerous long phone calls to Microsoft Support but have got the run around each time.  I rarely use Word & Excel so do not want to upgrade to Microsoft 365. I know it's possible to install on the new computer as earlier this year I installed on a different computer that had to be returned to Costco as it had issues.

Any help is appreciated!

    Good day Jennifer,

    Please note that I do not work for Microsoft, but I am an IT professional and will assist you as best as possible.

    It would appear that you have a two part problem.

    • You are using a version of office that is no longer in support with Microsoft.
    • Your installation media isn't matching your product key and therefore not activating.

    First task:

    Remove any previous versions of office.

    Microsoft has released a tool to do this.

    Please visit the below and follow the steps to clean any old versions of office.

    Your next task to resolve the issue will be copying the files from your original installation disk.

    You have two choices.  Purchase an external DVD/CD drive (they are not expensive)  Or get a friend with a computer that has a DVD drive and copy the contents of the DVD/CD to a USB drive.

    Once the contents is copied , you will run the setup file on the USB drive to begin the installation.

    While this work around might get office installed/activated for you, I would recommend upgrading your office package to a supported version.

    Please note the following non-subscription based Office packages are in support with Microsoft, and helping out without a legacy version will always be "best endeavors"

    Office 2021 for Windows – support ends 13 October 2026

    Office 2019 for Windows – support ends 14 October 2025

    Office 2016 for Windows – support ends 14 October 2025
