Had the same error for build 10049 and so when i saw that build 10061 was available, i was excited that I wasn't gonna be stuck on build 10041 only to get thrown the same error again. :( I've tried everything else but nothing works. All other updates (Windows Defender, Synaptics Drivers, AMD Display Drivers) all work well however. It's just the fbl_impressive Professional 10061 that fails.
Windows 10 Pro TP 10041 (64-bit)
Dual boot with Linux-manjaro.
Hard-drive partition with windows already set as active partition (after a suggestion that this was setting off another error)
Thanks alot! look forward to a solution that actually works.
