Hi Gerry, Thanks for posting here in the Microsoft community, you can try this.
To install Office 2021 without getting Microsoft 365 simply go to https://setup.office.com, Sign in with your Microsoft account then Enter your product key and click Redeem then Even if it mentions “Microsoft 365 Supplement,” it’s just a license agreement, you’re still getting Office 2021.
After redeeming, go to your Microsoft account > Services & subscriptions and download Office 2021 from there.
You’ll get Word and Excel as part of Office 2021 no subscription needed.
I hope this helps you out.
