ATL COMC++ VB deplyoment error System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory..due to the following error: 80040154.

Question

Hi,
I 've build a com  unmaneged c++ using atl. I used it in excel and all is fine.

I created an application in vbnet ,, and added the com dll as reference to the project.

THe project works fine both in debug and release mode.

Today I have added to a setup project  and added the primary output of the vbnet application.

If I install the app in other machines the application start, and works but when there is a call to the com dll function
I receive the error
system.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory..due to the following error: 80040154.

How can I distribute the app?
( i tried to reg dll, adding the tlb file... and so on) . The projects are x32

VS2008 framework 3.5 all machines xp sp3  32bit.

I am a newbye and I should resolve this problem  by the next week!


thanks in advance
g.

Hi Giacomo76,

I am moving this thread from Base ".Net Framework Setup" forum to the "Visual Basic General" forum, since the issue is related to VB programming. There are more VB experts in the "Visual Basic General" forum.

Thanks

Hi Giacomo,

Did you install that C++ COM component in target computer? You need to install that COM component and register that COM component in target computer.

Or you can use Registration-Free COM to deploy your application without registering COM component in target computer. Registration-free COM interop activates a component without using the Windows registry to store assembly information. Instead of registering a component on a computer during deployment, you create Win32-style manifest files at design time that contain information about binding and activation. These manifest files, rather than registry keys, direct the activation of an object.http://msdn.microsoft.com/en-us/library/fh1h056h(VS.80).aspx

Best regards,
Riquel
