I have a vb6 DLL which I want to call from a vb2008 project. I've added a reference to the DLL, turned on the "Isolated" property on the reference, and published the project.

However, when I install on another computer (or on my computer after unregistering my development version of the DLL), calls into the DLL fails. They work fine if the dll is registered with regsvr32.

What am I doing wrong? Why isn't the DLL isolated when I set "ISOLATED"?
