Windows 10: Problem with entering Product Key for Office

I recently reset my windows laptop. I had to reenter the Product Key for Office. I purchased this previously. I entered the Product Key and it says site cannot be reached. I hit reload and nothing. Troubleshooting does not reveal anything. I'm trying to gain access to some of my files and need Office to work. Please help. I've triple checked the Product Key and do not understand why it does not work? Yes, it's almost 10 years old but it worked fine up until a month ago.

Problem Activating Office 2019

You can save a few steps and do this

1. Go to this page: Microsoft 365
2. Log in with your Microsoft account
3. Enter your Office product key
4. Use the link given to download Office 2019
5. install Office 2019

I used this method for both of my copies of Office 2019

BTW, Microsoft Toolkit 2.71 says this:

Office problem with entering key

I have an old pro 2003 Office program disk that I have used on several computers and versions of windows. I had it working on my new computer but had to do a reboot and now when I try to reinstall Office it tells me that I entered the wrong key. I tried the same disk on my laptop with win xp and it worked.
I believe my present problem is because my new computer had Office 365 on it and has expired. I did a complete uninstall of Office365 and also used a program "015ctrremove.diagcab" but still no success in getting it to except the key.
My old 2003 Office did everything I needed so I don't see that I need to pay for a new Office365.
Any suggestion will be appreciated.
PS... I hate win10

 

Office problem with entering key

Is Office 2003 still running on 2 computers? If so the limit has been reached unless it's the Enterprise/Open License version intended for businesses. The EULA [End User License Agreement] specifies it can be installed on a work station and a portable device in control of the same person. It works to use more modern terms of desktop and notebook/laptop. I've not had problems Uninstalling the included Office trials from new computers before installing an older full version of Office. Most features of the Office suite work on Win10 except maybe Outlook and more-advanced formatting. I'm running Office 2000 on the Insider Preview of Win10 but only need a few of the basic features in Word and PowerPoint.
