Not enough space available - Service Pack installation

Not enough space available - Service Pack installation

I am trying to upgrade from 8.1.0 Build 8116 to 8.1 Build 8119  

When attempting to do so, I receive:
Not enough space available for installation of Service Pack

I am able to run the backUpData.bat routine and have about 300MB free (not a ton of space, but this should be sufficient?) on the drive SDP is installed on.

Is there anything else I can look into?
