I am getting an error "Creating an instance of the COM component with CLSID {648A5600-2C6E-101B-82B6-000000000014} from the IClassFactory failed due to the following error: 80040112"

I am using a MSCommLib.MSComm ( Microsoft Communication Control 6.0) controller dynamically to connect with the Com Port. The application works fine in the developer server. But in the client machine its giving an error. While goolgling I found that this error is raised because dynamic Run time Licensing for Microsoft Communication Control 6.0 is no. and I tested it and found true. Please help me to sort this out.

NB: This is a C# application

Baji, can I ask why you are not using the native SerialPort class to connect to the comm port that is provided by the .NET2.0 framework?

Solution 1

The best option would be, as already suggested, using the Serial Port[^] class provided by the .NET Framework.

If you're curious about providing runtime license info for COM controls, then you may have a look at my article "LicenceProvider"[^] (Note: is C++ code), it uses just the MSComm in the code sample.

Hey guys!
I had the problem too
I was testing my setup application into a virtual windows xp (I used VMWare and installed a new windows inside)
when I was trying to start listening on tcp server it throws this error.
I tried in an other system (not virtual) and it ran perfectly!
good luck
