Error: class not registered -2147221164

[Adriano]

I'm developing one integration between a Dll written in Visual Basic and Labview, but after installation and registration when i try to launch the application that calls its class i get error message: "class not registered -2147221164". While i'm developing the application i get all the properties and the methods from the class and i'm allowed to configure everything.
Hints, suggestions.. tips or tricks, please.
Thanks!

One idea.
Is the version of VB the same between development and executable?

Adriano,

Since I am not an expert in VB programming, I am just guessing a little here. Does your VB DLL use any other VB DLLs? I am guessing that since LabVIEW can see the methods and properties, everything is correct from our side, but when the VB DLL calls something internally, it is not found and the error is propagating upwards.
