Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Good day Scott,
Because the Microsoft 365 page loads slowly and the Install apps option doesn't respond, the issue can be caused by browser cache, browser extensions, network restrictions or your account's assigned license.
Please try the steps below:
Open an InPrivate window in Edge or an Incognito window in Chrome.
Go to office.com and sign in again.
Go to Apps and more > More apps > Install apps > Microsoft 365 apps > Apps & devices > Install Office.
Please also ensure your browser is updated to the latest version.
If the issue still persists when using a different browser, you may consider downloading Microsoft Edge and then repeating the steps above.
If you are unable to install the Office desktop applications, please contact your organization's IT administrator to verify your license and confirm that your account is assigned a license that includes the Microsoft 365 desktop apps.
Note: In case you do not know who is your IT admin, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support
For accounts assigned a license that includes only Office web apps, installation and activation of the Microsoft 365 desktop applications aren't available. Instead, you can sign in to office.com and select Apps and more to use the Office web applications through your browser.
Should you have any questions, please don't hesitate to reach out.
Thank you for your patience and understanding.
