Having this same issue on our first delivery of Optiplex 7050s.

Please Advise.

Having issues with CCTK on the 3050 also at 1.3.5. I downgraded it to 1.2.0 and everything works for it. Obviously not a solution, but just FYI.

Thanks bellenburg, so far Dell support have failed to acknowledge the existence of Bios 1.3.5, support for me so far is going round in circles, and keep saying 1.2.0 is the supported Bios.

I know this but they still wont answer why we have 1.3.5

@ bellenburg, 

Updated BIOS (1.3.7) with the fix is available on Dell support site:

http://www.dell.com/support/home/us/en/19/product-support/product/optiplex-7050-desktop/drivers/advanced  

Please verify with the same.

They have 1.3.7 posted, but don't have 1.3.5 posted. What fixes were in 1.3.5 (I want to see if it's worth updating to 1.3.7 from 1.2.0)?

Hello.

I clear TPM every restart and it works (in BIOS>Security>TMP2.0 check the box CLEAR)

I hope this help you
