Error Message When Attempting dcpromo.exe

Hello,
I am trying to install a new Windows 2008 R2 Domain Controller into an existing Windows 2008 domain.  When I run dcpromo on the R2 server, I get the following message:
"To install a domain controller into this Active Directory forest, you must first prepare the forest using "adprep /forestprep".  The Adprep utility is available on the Windows Server 2008 R2 installation media in the \support\adprep folder.

The old domain controllers are running the 32-bit version of Windows Server 2008.  When I run adprep on them, I get the following:
Forest-wide information has already been updated.
Adprep did not attempt to re-run this operation.

Any assistance is greatly appreciated.

You will need to run the adprep32 from the 2008R2 dvd in your 2008 server. It sounds like you are running the version of adprep from the 2008 server.

Should have posted the path as well

"\support\adprep\adprep32.exe"

Ken,
That worked. Do I need to run anything else (like domainprep, etc.)?

I attempted to run dcpromo on the new box and get the same error. Forestprep did run successfully on the old 2008 x32 server.

You will need to run /domainprep and /forestprep using adprep32 on the 2008R2 dvd.
