Returned Error - 259 when trying to install deployment package

I've created a full package using our college's education license (device) but the install fails within 10 seconds.

I can't find any record of this error on any forum or Adobe site.

I get the same logs on dozens of different machines, so I'm presuming the network location of the install is either corrupt, or inaccessible (although our older packages still work from the same location).

Anyone else experienced this?
