As a developer, I install and uninstall all sort of programs on my system so I am not surprised when some weird and random error message popped up.
I ran into the following error dialog today when I was writing some .NET integration code with EMC AppXtender.
This exception was thrown when I was trying to create the AppXtender DBConnection object. So I fired up the AppXtender Document Manager to verify my installation and it ran successfully.
Going back to my Visual Studio project, I verified the Interop.AEXDBLib reference and that seems right. A quick search on MSDN on error code 80040154 showed a list of COM errors on 32-bit OS, and I am seeing this error on my 64-bit OS.
The fix is to change the Platform target of my .NET solution to x86.

Hope this helps.

I had a similar issue and switching to x86 helps somewhat solved the problem, the only issue I have is that .NET would let me debug the code (it would not hit any of my brake point). I have another question about AX. AEXDBLib.ObjectFile object has a method CopyTo(), is there a way to get a file type. For example if it’s either DOC, DOCX, TIFF, of PDF, this way I can assign proper extension to the file when using CopyTo() method.
