Packager fails with "Maximum file path name exceeded" on InCopy

Question

Attempting to build the full suite with CCP 1.5.0 Build 83, running on Window 8.1 update 64-bit.
When building a 32-bit package it reaches InCopy it always stops and provides the so helpful "Maximum file path name exceeded error".  This appears to only happen when building the 32-bit package, building the 64-bit package caused no issues, and even in building the 32-bit package after the 64-bit package when everything is already downloaded the same error occurs.
Tried it with:
Cache path: C:\Users\iholmes\AppData\Local\Adobe\CCP\
Destination path: F:\ISO\Adobe\Cloud\Working\CreativeCloud-06192014x86
Also tried:
Cache path: g:\Adobe\CCP
Destination path: f:\cc\x86
These are all local paths, not mapped network drives.

Same here. From: C:\Users\<user>\AppData\Local\Temp\PDApp.log:
  <errorType>LongPathError</errorType>
  <filePath>C:\Users\<user>\AppData\Local\Temp\{839FDA1E-684B-4164-A8A0-AC83A4D37D3F}\AICY\ LS20\10.0\InCopy_10_LS20_Win32
I can manually extract the zip file from:  C:\Users\<user>\AppData\Local\Adobe\CCP\AdobeCCPCache\AICY\LS20\InCopy_10_LS20_Win32.7z to the above path (which I think is what it's trying to do) with no error, so it seems to be something Adobe is going to have to fix.
Someone else worked around it by creating a local user with a single character as the user name: Creative Cloud Packager Keeps Failing on InDesign: "Maximum File Path Name Exceeded"
