IIS7 ADODB VBScript runtime error '800a01ad' Classic ASP - read lots, cannot resolve

Thanks for reading ;

I have installed IIS 7 on my dev machine after a drive crash. Previously running IIS 6. Most sites I have use Classic ASP and use the following code ;

Set con = Server.CreateObject("ADODB.Connection")

I'm now getting the following error ;

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


I've researched this for weeks and have tried heaps of suggestions that I have read on various posts, nothing works, which is incredibly frustrating.... Running Windows 7 64Bit

a) Application Pool is set to "Enable 32-Bit Applications" TRUE (also tried FALSE)
b) ADO is installed
c) Permissions is set to Read/Execute for IUSR [machine] and have also tried the same for "Everyone"


Really would appreciate some help on this otherwise the only option I cam see is going back to IIS 6 which I'd prefer not to do.

thanks
