Failed to load dll 'iclit09b.dll'

Question

After installing the Informix server and Informix client, I encounter the following problem when trying to start an ASP.NET application:

unable to load DLL 'iclit09b.dll': The specified procedure could not be found.
(Exception from HRESULT: 0x8007007F)`

Answer 1

See where yours is iclit09b.dlland add this directory to your environment PATH.

You can use my simple “Python dll tester”: http://code.activestate.com/recipes/576522-searching-dll-and-exe-files-in-path/

On my machine, it gives:

c:\tmp>which_dll.py iclit09b.dll
2010-09-29 12:16:56      1004032 [b]    C:\informix\bin\iclit09b.dll
    trying to load "iclit09b.dll" ...
    C:\informix\bin\iclit09b.dll loaded

You can also try to configure the database connection using the ODBC manager, and iclit09b.dllODBC is used.
