**TL;DR** To solve it, use the latest abbodi1406's [KMS_VL_ALL](https://github.com/abbodi1406/KMS_VL_ALL_AIO/) or [MAS](index.html) to activate Office.
- Office Click-to-Run builds (since February 2021) that are activated with KMS check the existence of the KMS server name in the registry. If the KMS server is not present, a banner is shown in Office programs notifying that "Office isn't licensed properly"
- In the case of 32-bit Office installed on 64-bit Windows, Office checks the KMS server existence in the corresponding WOW6432Node registry key as well.
- Please note that these checks are not performed by Office if the proper installation of the Volume version of Office is done with Perpetual2019 / 2021 VL channel.
As mentioned in the reasons section, these checks are performed only if Retail Office is installed and later converted to VL. The office doesn't perform any such checks if the proper installation of the VL office is done.
- If we change the Insider or Current update channel **to** Monthly Enterprise or Semi-Annual channel then such non-genuine banners won't appear by default.
- Before doing this, make sure your Office update channel is either Insider or Current.
