Problem calling dll function with parameter in Inno Setup
I am successfully calling a function in a DLL from Inno Setup,  however upon returning I get a Runtime Error...Exception: Access violation at address XXXXXXX. Write of address XXXXXX.

The function is declared as:

    function CompleteInstall(szIntallPath: String) :  Integer;
    external 'CompleteInstall@files:InstallHelper.dll stdcall setuponly';

And called:

    procedure CurStepChanged(CurStep: TSetupStep);
    begin
       if CurStep = ssPostInstall then begin
          CompleteInstall('Parm1'); // ExpandConstant('{app}')
       end;
    end;

There is no problem if I change the function to not take a parameter. It still occurs if I change it to take a single integer parameter or declare it as a function and change the function to be a void function with an integer parameter.

The called function does nothing but return:

    __declspec(dllexport) int CompleteInstall(char* szInstallPath)
    {
        //AfxMessageBox ("Got here" /*szInstallPath*/, MB_OK);
        return 1;
    }
