Exchange Server 2010 Enterprise Install

Good day Everyone:

Ive been having serious issues with a new install of Exchange 2010 Ent Edt into a VM housing Windows Server 2008 both 64bit, I am able to get past some of the required steps but when it comes to preparing the schema it fails with the error below. just a bit of history on this, last year i attempted the same thing, i got to successfully install Exchange 2007 in a VM enviroment but could not keep the server due to lack of resources on our ESX server. I uninstalled it via Add/Remove Programs and then proceeded to dedlete the VM. I was on the phone today with Microsoft and they seem to think the schema preparation from last year upgraded the schema and is some how causing issues when it comes to the 2010 schema upgrade.

any help on how i can clear this message so that i may proceed with the install would be deeply appreciated, currently this little snag is holding up a p2v migration of our mailboxes. just a heads up we do have an Exchange 2003 physical box that is currently housing out mailboxes. Error below:

Thank you all in abvanced.

Found the issue with the install, Microsoft was able to determine the version number was not entered in the schema, we had to manually enter it to trick the install since the 2007 schema update i performed last year did not complete successfully since we had to scrap the Exchange 2007 deployment due to lack of resources.

other than that had the schema update been successful in 2009 with the exchange 2007 intended deployment the install for 2010 would had been seamless. thank you everyone.
