Can't install to MAPPED drive

The updater tells me I can't install to a UNC path and that I have to map the drive.
Problem is; If I map the folder containing the folder I still get the network mapping error. If I map to the actual folder where the program runs from I still get the error.
It appears as though the updater will not run from a network path, mapped or otherwise even though the message box clearly states it will.
Is there something to this I am missing? I can run the installer on my local HD then copy all that stuff to the NAS where it should be anyway but I would like to be able to save the files to the location they would wind up anyway. That would just make things easier.
