What I really need is clarifications. Was following instructions from Microsoft how to 365 apps where alraedy downloaded new. Opened word went to main account window and started when a disclamer at bottom of option section stated if I bought the office suite or 365 subscription the main set up has to be done in office app or wont be set up in all apps that were in package. I think what it saying is i can set up the main office if I start with word have to fill out 6 other apps independently

@ricochet,

Which Office product do you have? Typically, you need to associate your product with an account and then you install from that account at https://account.microsoft.com/services.

On a PC, you may have trial versions of an Office suite or the Microsoft 365 dashboard app preinstalled.

Often, you have to uninstall preinstalled versions before you install the one you are actually paying for.

Please go to https://www.office.com

Sign into the Microsoft account you used for the subscription. Click on Apps on the left.

Then on the upper right, click on "Install apps". This will now download the installer file. Once downloaded, click on the file to install. It will install the Desktop version of the apps for you then.

To reinstall Microsoft 365, follow these steps:

Uninstall Microsoft 365: If you haven't already, ensure that Microsoft 365 is completely uninstalled from your device. You can use the Microsoft 365 Uninstall troubleshooter to help with this process. Make sure you are using the same Windows device where Microsoft 365 was installed and that it is running Windows 10 or a later version.
Restart your device: After uninstalling, restart your computer to ensure all changes take effect.
Install the correct version: Go to the Microsoft 365 installation page and sign in with your Microsoft account. From there, you can download and install the correct version of Microsoft 365 that corresponds to your subscription.

Make sure that the bit version of Office (32-bit or 64-bit) matches your version of Windows to avoid compatibility issues.

Follow installation prompts: Once downloaded, follow the on-screen instructions to complete the installation process.
Activate Microsoft 365: After installation, open any Office application and sign in with your Microsoft account to activate your subscription.

If you encounter any issues during the installation, consider running the Microsoft Support and Recovery Assistant tool for additional help.
