Installing Office 2021 for home and student on MacBookAir with Monterey

Thank you for replying to me. I trashed anything related to my old Office package before I installed Monterey. Monterey took forever to install because I was several systems behind. Seems to me Monterey also mentioned removing Office well into the installation process. I would have followed what was suggested. Once installed, I saw no trace of Office products. Then I purchased Office 2021 from eksoftware who sent a link to uninstall any old Office product, Microsoft_Office_License_Removal_2.7.pkg. And then a link to install the purchased Office 2021 product,Microsoft_Office_16.62.22061100_BusinessPro_Installer.pkg. When done, clicking on Word, a screen pops up about Microsoft privacy settings. Word opens up behind it. No further clicking on either one does anthing. Only Force Quit - Word makes both close. I'll include a screenshot of what I see.

Today I contacted eksoftware where I purchased Office 2021 at 888-565-9142. I connected immediately with a technical support person. He took control of my screen and completed the uninstall and reinstall remotely. I realize that when I initially cleared my old Office into the trash, a big mistake I believe was not emptying the trash before I installed Monterey. This technician was highly skilled and got Office 2021 running perfectly. A friend will purchase the one-time install from the same source tomorrow. She has a new Mac with Monterey already installed but we'll carefully run through ek's suggested steps and links for Office 2021. Knowing the superb support available gives me great confidence to get it right this time.

Thank you for responding to me. You are so right about trashed. I put everything Microsoft in my trash but did not empty it. Major mistake. I called the vendor, eksoftware, about the software I purchased and connected with highly skilled tech support. By controlling my computer remotely, Office 2021 was uninstalled and then reinstalled. No problem with the Product key or anything else. Fantastic! I tried connecting with Microsoft prior to this with much frustration. A friend will purchase the same Office 2021 tomorrow from eksoftware with no anxiety especially knowing human help is readily available.

I also tried to reinstall Office but a message told me the product key was already used.

That makes good sense; this will be my plan.

You are very much appreciated for taking the time to reply to my Office install problem.

Thank you.
