hi we bought an hp compaq dc7600 ultra-slim desktop business pc
we try to use the truosers tpm_tools
when we want to take the ownership of the chip we have this problem:

[root@localhost tpm_mgmt]# LD_LIBRARY_PATH=../../../oricla ./tpm_takeownership -l debug

Tspi_GetPolicyObject success
Tspi_Policy_SetSecret success

we looked at the codes and also try with all te testsuite and verify the same problem(Tspi_TPM_TakeOwnership  returned (33) TCPA_E_DECRYPT_ERROR)
