Upgrade Win 8.1 tablet to 8.1 pro with Volume license key? Acer Aspire 10

Hello.. I have a batch of Acer Aspire 10 tablets that came pre-installed with Windows 8.1.  I need to upgrade these to 8.1 Pro so that I can attach them to my domain.  

I have a Volume Licensing Agreement that allows me to upgrade all my OS's, but I cannot quite figure out how to make it work with these tablets..  All efforts to upgrade them with the .iso from the VLSC have failed.  I have NOT deleted any partitions or tried a fresh install.

I am assuming the issue probably lies with the OEM License key embedded in the Bios.

I have tried an in-place upgrade with my GVLK (I use a kms server). but have tried the mak as well.  I have tried running the upgrade from the CD (form boot and the OS and from a mounted ISO.  When running from the OS, it seems to go through the entire process, but at the very end it sets everything back.

My license and the software assurance should allow me to do this, but I am at a loss.  Any help would be greatly appreciated..

All you should need to do is navigate into Windows Update and click on Add Features to Windows 8.1 (lower left corner) and enter the product key to unlock the additional features of Windows 8.1 Pro.

Worked fine on Samsung Ativ Tab.

There is a known bug in Acer's implementation of OA v.3 (the reading of the activation code from the UEFI BIOS) which tries to force an OEM install inrespective of media.

You may be able to force the change of OS licence by editing the ei.cfg file in your VL install media but with most of Acer's first line support being "unaware" of the problem getting Microsoft's activation team involved is probably the quicker route to get hands on help.

Disabling UEFI and flattening the drive should also prevent the embedded activation process interfereing but for 10 machines it's a lot of extra effort.

You are not alone, see:
