Thank you for your answer. i got it activated. if i have already used MAS_activation, i can remove that one and use this file for activation?
If you create a new VM or copy an existing VM and select "I copied it" when prompted you will get a new UUID. That may be enough to invalidate MAS HWID.
No, this mod is specifically for the VMware BIOS/EFI. If your physical Dell or HP server has a 2.7 SLIC, you can activate Server 2025. If not, you'll need to modify the server's BIOS/UEFI. To check if a modded version of your firmware is already available, visit the BIOS Mod or BIOS Mod Requests subforums.
