I’ve faced with following problem:

I have an ActiveX Control , on dev machine it is working as expected ,
when trying to create it on other machine I am getting the following error

Error: The system cannot find the file specified.

I am using following line to create it:

 var activeX = new ActiveXObject("ScannerViewerControl.ScannerViewer");

I’ve used installshield for deployment , and marked .NET Com Interop.

I am able to find in registry path to the .dll under HKEY_CLASSES_ROOT.

What am I missing ???

    You are probably missing a dependency for the active-x DLL on the client machine. Depending on what version of VS you have installed, you might have a tool called depends, which you can point at a DLL and see the dependencies that are required.
