IIS 32 bit DLL working in 64 bit IIS 6.0 problems

I am trying to get a 32 Bit DLL to work properly in an IIS 6.0 64 bit O/S

So far I have:

 - cscript.exe adsutil.vbs set W3SVC/AppPools/Enable32BitAppOnWin64 true

Also, I have set "Run WWW service in IIS 5.0 isolation mode" as checkmarked.

Then I have re-installed (several times) my DLLs using regsvr32 and rebooted.

I still get the same error message:

Microsoft VBScript runtime error '800a01ad'
ActiveX component can't create object

Is there something else that I am forgetting to do here ?  I have also tried configuring the security to run as Administrator thinking that it might be a security issue.  Still no luck.

You may have to enable the DLL as a 'Web Service Extension'  http://msdn2.microsoft.com/en-us/library/ms228213.aspx

To run the 32-bit version of ASP.NET 2.0, follow these steps:1. Click Start, click Run, type cmd, and then click OK.
2. Type the following command to enable the 32-bit mode:
cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1
3. Type the following command to install the version of ASP.NET 2.0 (32-bit) and to install the script maps at the IIS root and under:
%SYSTEMROOT%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i  
4. Make sure that the status of ASP.NET version 2.0.50727 (32-bit) is set to Allowed in the Web service extension list in Internet Information Services Manager.
