I want to be able to continue subscribing to Microsoft 365 and use Office 2021 for Publisher. How can I do this on the same computer?

    I just purchased a perpetual license for Office 2021 for the express purpose of using Publisher. Would this be considered a LTSC?

    The LTSC version is a volume license, intended for (large) organization such as businesses. It is not a valid consumer (home use) license.

    To run Publisher, you will need Office Professional 2021. Finding such a license today, when it is no longer sold by Microsoft, may be a challenge, though. Be very careful so that you don't buy a fake product key from a scammer.

    To use Microsoft Publisher from Office LTSC 2021 while maintaining your Microsoft 365 subscription, you can install both on the same computer. Here are the steps you can follow:

    1. Install Microsoft 365: First, ensure that you have your Microsoft 365 subscription active and installed on your computer. This will provide you with the latest versions of applications like Word, Excel, and PowerPoint.
    2. Install Office LTSC 2021: Next, you can install Office LTSC 2021, which includes Publisher. Make sure to download the version that is compatible with your operating system (Windows).
    3. Choose Installation Method: When installing Office LTSC 2021, use the Click-to-Run installation technology, which allows you to run both Microsoft 365 apps and Office LTSC apps side-by-side without issues.
    4. Activation: Ensure that both installations are activated properly. Microsoft 365 uses a subscription model for activation, while Office LTSC 2021 can be activated using a volume license key or through Key Management Service (KMS).

    By following these steps, you can successfully use Publisher from Office LTSC 2021 while keeping your Microsoft 365 subscription active on the same computer.
