Hello everyone,I am making application which uses webcam as barcode scanner.Every thing works fine,but when i run that app in win7 laptop,it throws the error
Retrieving the COM class factory for component with CLSID {5D34E962-9F95-4D92-917F-F9B1A4F2BC6E} failed due to the following error: 80040154. I have applied all the changes suggested through so many forums by developers but i am not able to correct that yet.i have added reference to DLLs, also registered them with regsvr32.exe.still facing the same issue,any helpful Suggestions please?

This error is most likely caused by trying to do 32-bit automations on a 64-bit operating system. In Visual Studio - project properties - in the Build tab - platform target = X86 or Any CPU

Kind regards,

Well, what about all of the assemblies called by the application and their bit version? Have you tried running this on a different Win 7 PC - just to check the result?

i have applied following things.1)added wialib.DLL2)added process manager as well as list and wiaaut dlls.3)changed target platform (x86,any CPU)4)changed permissions from COM config to allow .net user access.
