An error occurred while creating the IIS virtual directory

OK, included here is a portion of my exchangesetup.log for review.

I removed Exchange 2007, I demoted the Windows 2008 server, I removed it from the domain.  I added it to the domain, I promoted the server, it has all 5 of the roles from 2008, there is also a 2003 DC in the domain, this is the only instance of a mail server in the domain.

I am installing the 64 bit version of Exchange 2007 SP1

I installed the Management Tools and Hub Transport with no problem, when it got to CAS it failed because the OWA directory was there.  I stopped, removed the directory, uninstalled CAS from the command line and tried again.  I have tried everything I can find and still get the same error.  

If anyone has any further instructions or ideas, I am in dire need.

Thanks,

---------------------------------
1)  I have removed everything from IIS, then I removed IIS and reinstalled it since I keep getting this error.

2)  I have deleted everything in the C:\inetpub\History directory (a keep deleting it every time it fails, it always has these lines in the history file:

<key path="LM/W3SVC/FILTERS/COMPRESSION/gzip">
      <property id="2215" dataType="DWord" userType="1" attributes="None" value="1" />
      <property id="2238" dataType="MultiSZ" userType="1" attributes="None" value="htm&#xA;html&#xA;txt&#xA;htc&#xA;css&#xA;js&#xA;xsl&#xA;docx&#xA;doc&#xA;xlsx&#xA;xls&#xA;pptx&#xA;ppt&#xA;mdb&#xA;" />
       <property id="2244" dataType="MultiSZ" userType="1" attributes="None" value="owa&#xA;aspx&#xA;eas&#xA;" />
</key>

and these:

 <application path="/owa/8.1.359.2" applicationPool="MSExchangeOWAAppPool">
                    <virtualDirectory path="/" physicalPath="D:\Exchange Server\ClientAccess\owa\8.1.359.2" />
</application>
<application path="/owa/8.1.375.2" applicationPool="MSExchangeOWAAppPool">
                    <virtualDirectory path="/" physicalPath="D:\Exchange Server\ClientAccess\owa\8.1.375.2" />
</application>


3)  I have utilized the IIS 6 script to force 64 bit processing

4)  I have searched my hd for any directory named OWA and there isn't one, I haven't configured IIS since I have reinstalled it, and there is no OWA in that interface.

5)  I have searched the registry for any reference to OWA and don't find one after I uninstall CAS.
