Barcode ActiveX Control Class not registered error

Postby bganesan on Wed Jul 03, 2013 1:29 pm

Hi,
We are using Morovia Barcode ActiveX Control 3.3 for 2D barcode generation in our window service application and it’s developed in Visual Studio 2010. We are using below mentioned DLLs for barcode generation.

 AxInterop.MrvBarCdLib.dll
 Interop.MrvBarCdLib.dll

We have deployed this windows service in Window Server 2008 R2 system. In this server if we run the our barcode generation window service, while accessing the Morovia Barcode ActiveX Control we are getting below mentioned error.

Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

Please let me know how to fix this issue?

Regards,
Ganesan. B

Barcode ActiveX is 32-bit DLL and require the host process to be 32-bit too.

If it is .net application, you need to compile it under x86 setting instead of "Any CPU" (default).

See http://mdn.morovia.com/kb/PRB-Net-Progr ... 10603.html.

Ganesan,

The next major release 5.0 will support 64-bit. However it may not be 100% backward compatible with the current 3.x version.
