Hello EE,

I have a form in vb.net with a OWC11 control

I have the references :

AxInterop.OWC11
Microsoft.Office.Interop.Owc11

It works very well on my machine.
works also at some clients.

there is one developer here that cannot open the form and he's having the error:

ClassFactory cannot supply requested class (Exception from HRESULT: 0x80040111 (CLASS_E_CLASSNOTAVAILABLE))

when loading the solution on his visual studio, trying to open the Design Form, Im having same error.

Both machine working and not working have same frameworks...has Office web 2003 components..


I dont know where to search anymore

can you help ?

Try reregistering the component using regsvr32.

it is saying:  C:\Elk\9_....\bin\AxInterop.OWC11.dll was loaded, but the DllRegisterServer entry point was not found.

this file can not be registered.


when I try to do instead:

regsvr32 "DLL C:\Elk\9_...\bin\AxInterop.OWC11.dll"
im having:

LoadLibrary("C:\Elk\9_....\bin\AxInterop.OWC11.dll") failed - The specified module could not be found

That's probably because its not a COM component. The AX*** is a .NET assembly. Did you try regsvr32 on the OWC assembly itself?

This would be in program files somewhere such as


C:\Program Files\Common Files\Microsoft Shared\Web Components\11\OWC11.DLL

It was a little related to that. I found the solution. I went to microsoft update then tried again. not working.  I have deleted from add/remove programs the Office 2003 components. then re-install it. It was still not working I went back to microsoft update and now i was seeing updates for Office compenents. I installed them then tried again and now I could successfully open my form.
