ok - i know i'm doing something wrong - but what?
i'v created a simple dll:
#include "windows.h"
#include "msi.h"
#include "msiquery.h"
extern UINT __declspec(dllexport) __stdcall test(MSIHANDLE);

// This is an example of an exported function.
__declspec(dllexport) UINT __stdcall test(MSIHANDLE hInstall)
{
return ERROR_SUCCESS;
}

i build the dll
i add CA to run function in windows installer Dll  from binary table, function name 'test', execution immediate
I add CA to UI sequence just before executeAction
i create the setup.exe
when i run the setup  i get error 1723 - this is on windows 2000, i have msi 2.0 installed but i am using ISWI 1.52.
What am i missing

You'll probably find that the exported function name in your DLL file has C++ decorations on it. To check, use a tool like Dependency Walker to view the exports.


If your exported function name is decorated, you'll have to put your exports in a DEF file. To do this:

1. Change the function prototype to:

Code Sample

extern "C" UINT __stdcall test(MSIHANDLE)

2. Create a new file with the same name as your C/C++ source file, but rename the extension to ".DEF". Enter the following text into the file:

Code Sample

EXPORTS    test

Recompile your DLL and check the exports again. This time it will be called simply "test"
