Trying to use manage-bde to turn on bitlocker

Im trying to use "manage-bde" to turn on bitlocker but I get error below that TPM is off but it is on. I did it manually by just right clicking the c drive,enabling bitlocker and it works fine. Anybody have any suggestions on why this is happening?
I am not using SCCM.

C:\Windows\System32>manage-bde -on c: -RecoveryKey "\\server\bitlocker\b
itlocker\bitlocker-%computername%.txt
BitLocker Drive Encryption: Configuration Tool version 6.1.7601

Volume C: [System]
[OS Volume]
ERROR: The TPM cannot be used to protect this volume. The TPM is off.

Type "manage-bde -tpm -?" for more information on configuring the TPM.

C:\Windows\System32>

Just do as the message advises, see what manage-bde -tpm -? has for you and what you can do with it. It could be that turning it on manually just implies some tpm commands, couldn't it?
