SEPM temp download temp files

I have a setup where I have the SEPM (12.1.3) built on a D: drive as there is not much space available on the C: drive. It's built with an embedded database. There is only 4gb available on c: drive when liveupdate tries to run on the SEPM it gets to download and then the embedded database service stops and won't start back up. 

 

Is this because the SEPM is writing the temp download files to c: drive? If so is there any way to move where it downloads them to? Or anything else it may be writing to the c: drive. 

 

I've tried refreshing the sem5.log this gets the database back up but then when liveupdate starts again the service goes down.
