Hi,

you don't need the MCR. See here:

http://www.mathworks.de/help/toolbox/dotnetbuilder/ug/bqey2vo-1.html

Do this for the MWComutil.dll and MagicDemoComp.dll. The mwregsvr command should be known if MATLAB or the MCR is installed correctly (mwregsvr resides in the same folder as needed DLL's). In the case it is not kown, make sure that the MATLABROOT\runtime\ARCH folder is on your PATH. (MATLABROOT = installation folder of MATLAB, ARCH = system architecture (win32 or win64)).

Since registering a COM DLL means modifying the registry, make sure that you have the permission for that.

In addition, you built a COM DLL, so you dont need the MWARRAY.DLL and you also don't need the mlapp.tlb

Hai , thank for the reply. I already done what you have suggest and follow the link ,

when i register the mwcomutil.dll using "mwregsvr mwcomutil.dll",

it success , "DllRegisterServer in mwcomutil.dll succeeded"

but i try "mwregsvr MagicDemoComp.dll", can't register ,

the error "Error: 0x0000007f Message: The specified procedure could not be found. " happened!

and i debug again in visual studio( already add reference to mwcomutil and MagicDemo ) , the visual studio give same error :

1.)Cannot load type library for reference "MagicDemoComp". Library not registered

2.) Cannot load type library for reference "MWComUtil". Library not registered.

but MWComutil aready succcesfully register , why still have this error ?

Where do you get this error: The specified procedure could not be found? On the development machine or on the deployed machine? When I would have to guess, I would say you get this on the deployed machine because the Visual Studio Redistributable package is missing.

[renoald Tang]

Yes, on deployed machine. But there not have any error when i install the visual studio. How i resolve it ? Uninstall and install again Visual studio ?

[Friedrich]

Just download the Visual Studio Redistributable package in the matching bitness and version and install it. That's all you should need. You don't have to install the full Visual Studio.
