Windows 7 upgrade Bitlocker problem

[Unregistriert]

Hi,

I upgraded my Vista to Windows 7. Turned off Bitlocker before upgrading. When I finally had Windows 7 on my computer I tried to turn on bitlocker again. It was not possible, so I decrypted the drive. Then I tried to encrypt the drive again but on reboot I got a message (bitlocker could not be enabled, TPM problem). Windows boots normally to the desktop but the drive is not encrypted. Anyone there who knows what to do to get bitlocker working again?

Thanks and greetings
Henning

I understand you so that you update on W7've done.
Your Bitlocker was previously decoded and now you have problems with the TPM!?
Your TPM will not be compatible with W7 as your only option is to create a network key ....
You simply read through the following links ...
