I've been asking this question, but seems still can't find the proper answer.
I would like to know what this means and how to avoid.
I understand that this is very common that most activation will show this line.
Please look at the screen caps from all the activation in this post:
I was told "all KMS batch file method here not accept multiple installation Office in same PC. Office 2019 must be only copy without other Office version in the same PC."
And yes, i can assure you , i have completely cleared all previous licenses by using command "cscript ospp.vbs /unpkey:XXXXXX"
I have also download the scrubbing tool from Microsoft to clear all residues of Office installation.
The Office 2019 i obtained was downloaded fresh from microsoft by using the deployment tool: setup.exe /download configuration.xml
Yet, after i install i will get the "activation BETA EXPIRATION: 01-Jan-1601" line, just like most other people here who activated. Please check out the screenshots here; https://community.msguides.com/d/56-office-2019-activation-issues
I did have one PC installed with exactly the same method, but no such line appeared. So my question is , what does this line signify , and what effect does it have>
For your information, my Office 2019 was kms licensed for 180 days no problem. I hope i made my point clear and am willing to learn from anyone what this line means.
Thanks very much indeed.
