Classic ASP METADATA Tags Not Working - MDAC 2.8/WDAC 6.0 on a Windows 2008 Box Running IIS 7

What I am trying to do is simple. I have some Classic ASP with include headers like the following referencing MDAC 2.5:

METADATA TYPE="TypeLib" NAME="Microsoft ActiveX Data Objects 2.5 Library" UUID="{00000205-0000-0010-8000-00AA006开发者_C百科D2EA4}" VERSION="2.5"

Now I am trying to call this same include file on a Windows 2008 box with IIS 7 using MDAC 2.8 with this:

METADATA TYPE="typelib" NAME="Microsoft ActiveX Data Objects 2.8 Library" UUID="{2A75196C-D9EB-4129-B803-931327F72D5C}" VERSION="2.8"

My question is, why does this not work anymore? Has the tag reference changed? I ran MDAC checker and everything is installed correctly. What am I missing?

I am running on a Windows 2008 box with IIS 7.

Thanks in advance!

You must set your site to run on 32-bit mode.
[EDIT]
MDAC 2.5 is only 32 bits
MDAC 2.8 has 64 bit version
