Solved How to enable BitLocker support (unlock drive) in WinPE 5?

Hi,

I have a Microsoft Surface Pro 2 and I am running Windows 8.1 Pro Update 1.

I have been unsuccessful at building a WinPE image that provides BitLocker support. I searched around the internet and found many posts. Eventually, I ended up trying to build it with the various added packages I discovered in the various posts. However, in the end, none worked and this is the message I am getting after booting into my WinPE environment:

manage-bde.exe - Application Error

The instruction at 0xa20afa3b referenced memory at 0x0000013d.
The memory could not be read.

Click on OK to terminate the program

Here are the commands I eventually ended up using to build my WinPE image:
But even with all that included, I still have the same error about the memory.

Does anyone have a WinPE 5.0 x64 bootable environment working on a TPM-enabled machine? If so, how did you build your custom WinPE environment?

Thanks!

I resolved the issue, but here's how I got to it:

1) I even tried using the 8.0 ADK, but I still got the same error.

2) At one point during my troubleshooting, I stopped just prior to performing the Commit to create the WinPE image. Then I navigated to the <mount directory>\Windows\System32 and ran manage-bde.exe. The result: A Windows error (something to the effect that the program crashed/stopped working).

3) I tried running Notepad.exe and it worked fine.

4) I compared the manage-bde.exe from my mount directory to the one in C:\Windows\System32 using the comp utility and they were identical.

5) I have always been able to run C:\Windows\System32\manage-bde.exe. So I created a "temp" subdirectory in my mount directory and copied C:\Windows\System32\manage-bde.exe. When I tried to run it, I got that error (program crashed/stopped working).

6) Running it from the C:\Windows\System32 directory, however, worked without any issue. This led me to conclude that it required some dependent files in C:\Windows\System32.

7) After a bit more troubleshooting, I discovered that in order for it to run, it needed something in directory C:\Windows\System32\en-US\. I copied that folder I into my "temp" folder on my mount directory and then manage-bde.exe was able to run without any issues.

8) Final solution was to create a subdirectory called "BitLocker" in <mount directory>\Windows\System32, then copy C:\Windows\System32\manage-bde.exe and C:\Windows\System32\en-US\ into it. Then I performed the Commit to finalize and create my WinPE image.

9) Upon booting my WinPE environment, in the Command Prompt, I change to the "BitLocker" directory and run
manage-bde.exe from there to unlock my BitLocker volumes. No errors.
