When running the AXupdateinstaller.exe devinstall on the platform update 12, the following failure error can sometimes occur: 

Due to Microsoft changing the admin rights on their VM images in a Microsoft subscription, there was a need to change our AOT package starting from Platform Update 12. Developers that are using AXupdateinstaller.exe devinstall to install our software will face the above error.

Applying the same package through LCS will work without any problems.

You can also request an AOT package specific to PU12 from your local Lasernet reseller.
