OK. That took longer than expected. I had a couple of days away from my desk in there so I apologize for not getting back sooner.
Ultimately, this is what worked:
Windows 7 Enterprise, SP1
KB2685811 installed into the .WIM
Chipset (sp72786)
Essential System Updates (sp72825)
Bluetooth from link provided by Paul_Tikkanen(BT_18.16.1_64_Win7.exe)
Thank you!
