I'm trying to enable bitlocker on win7 32bit. It said I need to initalize my TPM, the PC rebooted, I got a black screen that said I need to press F10 to allow the change. I did that. Booted back into windows. Went back to control panel system & security and enable bitlocker drive encryption. It has at the top "Initializing the TPM security hardware please wait while Bitlocker initalizes the TPM security hardware. This might take a few minutes. Access is denied." The progress bar never moves. I've checked the TPM is turned on in the BIOS. Any ideas ?

Check this blog post to see if it resolves the problem, otherwise please submit a screenshot of "tpm.msc" http://blogs.technet.com/b/askcore/archive/2010/03/30/access-denied-error-0x80070005-message-when-initializing-tpm-for-bitlocker.aspx ThanksTanner --- This is posted as-is and has no warranty or guarantee ---

I had problems enabling bitlocker. I followed these steps: 1) http://code.msdn.microsoft.com/bdedeploy/Release/ProjectReleases.aspx?ReleaseId=3205 2) Download the EnableBitLocker.vbs script 3) Open command prompt as an Admin 4) Run EnableBitLocker.vbs script to show a prompt w/ all options. I ran EnableBitLocker /on:tpm /l:c:\bitlocker.log /promptuser
