ColdFusion 8.01 install issue with Win2008 server

[martijr]

I am having an issue with the installer on ColdFusion 8.01 in Win2008 server.  I have done 5 or 6 identical installs with no problem so this caught me by surprise,  The server OS is Server 2008 R2 Enterprise service pack1.  I am running the install (coldfusion-801-win.exe) as an administrator in emulation mode (Windows Server 2003 service pack 1). The following is the error i get.   As I stated earlier I have done this exact install, both single & multi-server, on 5 or 6 Win2008 servers with no issue.  Any help would be appreciated.
