Did you install/register those components?

Does your Windows 7 happen to be a 64bit OS instead of a 32bit OS? If so, beyond installing and registering the ThiordParty components, you have to set the bitness of your application to 32bit (i.e. in the project properties under "compile" set the "target paltform" to x86 instead of "any cpu" or "x64").

yes 64bit OS targe platform is x86
System.runtime.interopservices.comException was unhandled is the runtime exception
