I have a virtual server (IIS7 on Server 2008 R2) on which I installed a COM-enabled assembly called by Classic ASP. "Enable 32-bit Applications" is set to true, and everything works.
But on a real server of the same kind, and on a different virtual server of the same type, I have to set "Enable 32-bit Applications" to false and THEN my Classic ASP pages can create the object.
What's going on?
