How did you install your app to that machine? Are you sure that COM library exists on that computer? Did you register its COM interface with regsvr32 there?

I installed it same as any other application is install.
Yes, the COM library exists on that computer.
Please tell me how to register its COM interface with regsvr32 there in 32/64 bit operating system.

Solution 2

If your COM-interface implemented in 32 bit, just launch the console (cmd.exe), then type

%windir%\System32\regsvr32.exe yourlib.dll

If you have some installation script, consider to use autoregisration feature (if its available)

If your library is for 32 bit architecture and target system is x64, you should use then DllSurrogate[^].

For more information about DllSurrogate, please refer the following link:

Please refer to the following link to register your 32-bit COM object on 64-bit OS:
Using a 32-bit COM Object from a 64-bit Application[^]

It is working fine in 32 bit operating system but having issues on 64 bit machine although i have registered the dll on 64 bit machine.
I got exception " Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))".

I just set target machine to x86 then build the application and it worked for 32/64 bit OS.
