Failed to install Sophos Autoupdate: The MSI has failed [0x00000067]

Hi,

I have 5 Windows Server 2012 R2 Servers that are displaying the above message continuously. I cannot seem to find anything to give me a clue to what is going on. I have checked the Sophos Autoupdate log in C:\Windows\Temp and it shows the following:

Any ideas? I am at a complete loss.
