E: is just a local harddrive. The full python install and files under 
the E: drive is accessible for both the local SYSTEM user, my user and 
administrator.

It is configured to run as the Local System Account.


I am successfully able to install the service initially via admin 
command prompt, and the run it via pywin service debug or using 
services.msc. But after performing several more service installs I then 
get this error. It regularly happens and stops any further services from 
running.

I can then reinstall python and it is resolved again.


I've asked IT to review any antivirus blocking of files/manipulation of 
files. They have confirmed there is not. Although I was going to perform 
checksums on the DLL's and pythonservice.exe.

      <p>To be clear, the entire Python tree will need those
        permissions, not just that .exe. And the question is whether the
        user running the service has access - SYSTEM and Admin should
        cover many common scenarios, but not all. You could try
        configuring the service for your specific user just to see if it
        works - if it does it would still point to user permissions.<br>
