Im using the SDK for the DYMO Label printer, what ive noticed is that when I build a project and then install it on a different machine, it will load correctly but when I start the program I get an error: REtriving COM Class factory for component with CLSID {09DAFAE2-8EB0-11D@-8E5D-00A02415E90F} failed due to the foolowing registry error 80040154.

When I load the DYMO hardware drivers on the same machine the error goes away, however some users may not have a DYMO printer and thus I need it to work without the drivers

Can anyone suggest anything?

So, that means you'll need to dynamically load the DLL after you've determined if the client PC has the drivers installed.
There are several examples on the Internet, here is a simple one:  http://blogs.msdn.com/jonathanswift/archive/2006/10/03/Dynamically-calling-an-unmanaged-dll-from-.NET-_2800_C_23002900_.aspx

Cant I just embed the .dll inside the compiled program?

Well, I was assuming that there was a lot of dependencies between the DLL and the "drivers".    So, including the DLL in the assembly (either as a discrete DLL or embedded) might not do the trick.
I'd recommend a quick test where you just alter the "Copy Local" property of the DLL in the References section to see

By going to the Reference "folder" in the Solution Explorer (typically in the upper right-hand corner, navigating to the reference in question, doing a right-click to get to the properties, then changing the Copy Local property to True
