Activator.CreateInstance throws error 8007007e -- "Specified module could not be found"

If it's located somewhere else, run "regasm
<dllname> -codebase" and it
forces the location of the DLL to be stored in the registry.

So I solved this one: it started working once I copied the
relevant DLL
in the bin subdirectory of the deployment directory, and
modified the
registry to reflect the new location. 

I also noticed that you get this error message as well if
one of the DLL
on which the first DLL depends is not found.

I assume the CLSID in question is installed on your machine.
(HKCR\CLSID\\Inproc
Server32).

If so, then can you create an instance of this component
using another
language or program?

Hi,

I apologize if this is a trivial question, but I could not
find any
documentation about this.

I have an web application where I need to load a COM
component. I use

System.Type type =
System.Type.GetTypeFromProgID("comName");
System.Object obj = Activator.CreateInstance(type);

and it works fine when running in C# from the command line
or when
debugging as an ASP page (with C# code-behind) from
VisualStudio
2005. However after I deploy the application to my PC I get
a message
that says:

Retrieving the COM class factory for component with CLSID
 failed due to the
following
error: 8007007e.

The error code 8007007e stands for "the specified
module could not be
found". Anyone knows what I need to do to correct
this? I tought either
the
path has to be specified differently or permissions have to
be adjusted,
but
I couldn't find anything in the documentation.

Thanks,

Alain
