RC2/Bitlocker/Non-TPM/ and gpedit error

I'm trying to follow the steps on switching on Bitlocker for Non-TPM machines
using gpedit.

When I run gpedit I get the following error "Error 64 Help String specified
more than once. The file cannot be loaded." in the following files:

c:\windows\inf\AER_2068.ADM on line 30:

c:\windows\inf\AER_3076.ADM on line 30:

c:\windows\inf\AER_2068.ADM on line 189:

c:\windows\inf\AER_3076.ADM on line 189:

When I click OK to these and continue with the steps Bitlocker Non-TPM still
doesn't work even after a reboot.

TIA

Jason
