SAV not installing?

Question

So I got a new small Dell laptop for some things to do on and I run a Sophos UTM 9.510-5 with Endpoint Protection included. 
 I download the file from the UTM, install as administrator and it will only install the Autoupdate features, and not at all installing SAV. No services, nothing. The same file using the same UTM has worked just fine with an AV install on my other home computers. 
 The laptop shows up in my computer group with the rest of my computers on the UTM as it is supposed to, but no AV is installed. The only other product on this Windows 10 laptop is Windows Defender, which has been the standard with every other install I have. 
 I don't see any errors in Windows log files, and the Sophos log just shows Autoupdate succeeding the install, mentioning nothing about AV.

This is a known issue and Sophos have refused to fix it. 
 
 Here is the countless threads here that document this issue:

 There is, however, a valid workaround : 
 1. Copy the Warehouse folder from a working endpoint (the warehouse folder is found at C:\ProgramData\Sophos\AutoUpdate\data). 2. Paste the folder into the same location on one of the affected endpoints. 3. Force an update/run the install. 4. Check to see if the affected endpoint has now updated successfully.
