I have some problem to install 6.0.4 LDAP SDK on Windows VIsta 64-bit.

Hi.
I'm trying to build the mozilla LDAP libraries on the Windows vista 64-bit.
I installed Malicrosoft Visual studio 2005 professional edition replacing 
express edition.
And I set the Windows Platform SDKs for windows server 2003 sp1 and windows 
vista.
I installed the mozillaBuid.
So I checked tools, bulid environment, redistributable componenets, and the 
menu "Open Build Environment Window".
I could not find winable.h and oleadd.idl from C:\Program Files 
(x86)\Microsoft Visual Studio 8\VC\include.
But I tried to install start-msvc8.bat and ran the batch file ans 
administrator.

The result is as following:
"Mozilla tools directory: C:\mozilla-build\"
Visual C++ 6 directory:
Visual C++ 7.1 directory:
Visual C++ 8 directory:
Visual C++ 8 Express directory:
SDK directory: C:\Program Files\Microsoft Platform SDK\
"Microsoft Visual C++ version 8 was not found. Exiting."

I don't know why VS version 8 was not found.

Any help would be greatly appreciated.
