Missing com class or dll

Hi,

I have an application that was written maybe 10 years ago. Runs fine on a xp machine. When I install it on windows 10 it runs but get the following error: retrieving the com class factory for component with clsid failed due to following error: 80040154 class not registered.

The application was written in VB.

I installed older .net versions in a hope it would help but did not. Would I be missing a DLL file and if so is there a way to find out which one I need to register?

Thanks
Fergus
