问题
I am following this tutorial (https://atgsupportcentral.motorolasolutions.com/content/emb/docs/manuals/14978403a.pdf), created a simple Windows Forms and successfully can debug it on the scanner (it's a Symbol MC3000).
However I am getting an exception when trying to initialize the CCoreScannerClass:
//Instantiate CoreScanner Class
CCoreScannerClass cCoreScannerClass = new CoreScanner.CCoreScannerClass();
The exact error message is this:
"COM object with CLSID '{9F8D4F16-0F61-4A38-98B3-1F6F80F11C87}' cannot be created due to the following error: 0x80040154."
Can anyone please provide some help? Since it's a COM exception, I assume it's because the class is not registered? Any ideas on how to fix this?
Many thanks.

I got it working by downloading the EMDK for .NET from the Motorola's website:

0x80040154 is an error that, as you mentioned, pertains to the COM class not being registered, which means that COM couldn't find the class factory in the Windows registry. You can use C:\Windows\system32\regsvr32 to register the missing SDK DLL.

I got it working after the installation of the Scanner Management Service https://portal.motorolasolutions.com/Support/US-EN/Resolution?solutionId=87864&productDetailGUID=f0acd085364cf310VgnVCM10000081c7b10aRCRD&detailChannelGUID=84a76e203763e310VgnVCM1000000389bd0aRCRD
