Live Migration Error - Migration did not succeed. Not enough disk space. (But there is plenty)

Hello-

I'm trying to do a shared nothing live migration between two Windows Server 2012 machines.  Unfortunately, I'm met with an error message of "Migration did not succeed. Not enough disk space at xxxx." when I attempt it.  The virtual machine is about 245 GB total and the destination has 1.54 TB free.

From what I can tell, the free space check is checking to see if there is enough free space on the target server's C partition instead of the D partition.  The D partition is the target for both the virtual machine and its VHDs.

The problem sounded kind of like what is described by KB2844296 (https://support.microsoft.com/kb/2844296), so I tried to download and install the hot fix.  The hot fix installer states "The update is not applicable to your computer."  I appear to be out of options.

I'm hoping someone else has run into this issue and has a workaround.  I don't see that there is much more that I can do short of shutting the virtual machine down, exporting it, and moving it manually.  I'd much rather use live migration.
