Server 2008 R2 in 2008 standard domain

Hi

i have 3 virtual domain controllers running sever 2008 standard (32bit). im trying to dc promo a physical server that i just installed server 2008 r2(obviously 64 bit).  when i attempt to dcpromo i get the error "To install a domain controller into this AD forest you must first prepare the the forest using "adprep /forestprep",..."  this error leads me to believe the domain is not running at 2008 functional level and it needs to be upgraded.  however the domain is running at a windows server 2008 functional level.  

nonetheless i tried to run the forest prep command using the 64bit r2 media on the PDC and will not run. it says its not compatible. this is the only part that makes sense to me


Do i have to reload this machine with windows 2008 standard as opposed to windows 2008 r2?  Is it possible to install an 2008 r2 OS in to standard 2008 domain?
