Frequently Asked Questions
Do I need the internet to use an offline installer?
Yes, you need an internet connection initially to download the installer file from Microsoft's servers. Once the file is fully downloaded to your computer or a USB drive, you can run it to install Office on a computer without internet access.
Why is Office Professional Plus 2021 not showing in my standard Microsoft account?
Office Professional Plus 2021 is typically a volume-license product. If it was purchased through an organization or a volume licensing agreement, it will only be available via the Microsoft Volume Licensing portal, not your personal retail Microsoft account.
Can I use the same offline installer on multiple computers?
Yes, you can use the same downloaded offline installer file to install the software on multiple computers. However, you will still need a valid, unused license or volume activation method to legally activate Office on each individual device.
