Optiplex 7040 Win7 x64 Bitlocker

Hey All!

We can't seem to get Bitlocker working on our 7040s, have any of you seen this issue and have gotten it to work?

Dell Optiplex 7040

Windows 7 x64

TPM is on/enabled in BIOS

TPM 1.2 driver looks good in device manager

But when we try and turn bitlocker on via right-clicking the HDD it gives us the "A compatible Trusted Platform Module (TPM) Security Device must be present on this computer, but a TPM was not found. Please contact your system administrator to enable Bitlocker" error/message

When we look in tpm.msc we see "Compatible Trusted Platform Module (TPM) cannot be found on this computer. Verify that this computer has a 1.2 TPM and it is turned on in the BIOS" error/message

Any thoughts?

We were able to enable bitlocker on this model when we deployed Win10 but we are still mostly on Win7 for now.

Thanks!

Marc V
