Issue after upgrading TPM firmware

Hello,

This is the update that I am trying to accomplish: Update your security processor (TPM) firmware

However after completing the steps that are listed within this article I am still not able to complete the actual upgrade. I still have the pop up that states i need to upgrade.

I followed the following steps:

1. ensure all upgrades are up to date.

2. download the specific .EXE firmware update file and run it on my machine as an administrator

3. clear TPM and restart.

however simple these steps are I have not been able to complete the update.

I am on a HP Z240 SFF 1.2 TPM

What can I do to ensure that my TPM is updated to the latest firmware?
