Administrator Can't Decrypt Bitlocker

[rayancaleb]

Hi,



I have a Windows 8.1 system that is joined to our corporate domain. I am the IT administrator so I have both a domain account with admin rights and a local account on the PC with admin rights.We encrypted this laptop way back when it was set up. The Lenovo software decided (well the user decided...) to install a BIOS update and now when the system boots we continuously get prompted to enter the bitlocker recovery key.



I've read on some forums the best way to fix this is decrypt the system, finish all the updates, and re-encrypt. However, when I go to the Bitlocker Drive Encryption control panel, it says "settings are managed by your administrator" (which I am).



So I was reading around, and I launched an admin command prompt and typed: cscript manage-bde.wsf -off c:

That gives this message:



Warning: The script manage-bde.wsf is not supported. Please use manage-bde.exe.

Error: An error occurred (code 0x80070057) The parameter is incorrect.



Please Help.



Thanks,



I didn't find the right solution from the internet.
