MS Project handling with php

I've created a small C# console program that handles and exports some stuff from MSProject. After I have installed Microsoft Server 2008, and tested my program from console. Then as a final step I've installed apache&php, but I couldn't force my program to work by php calls. I think it is permission errors, but I have added "Everyone" group to all exes(MSProject.exe, myconsoleapp.exe) also the msprojectfile.mpp with full controll(I know I shouldn't do that, but first I want it to work).

Some more things that i tried: I have tested if the input paramters from php are wrong. I have tested if other small program(exe, batch etc.) running. Tested severl version from local console. I have tried to give sleeps, since console etc...

Here are some codes:

php:

exec("C:\Apache24\htdocs\ConsoleApplication1\ConsoleApplication1\bin\Debug\ConsoleApplication1.exe C:/Apache24/htdocs/mympp.mpp 1 data1 data2 data3 data4 data5 data6 data7 data8 data9 data10 data11 2>&1", $output, $answer);
echo "answer = " . $answer;
var_dump($output)

ConsoleApp:

static void Main(string[] args)
{
    for (int i = 0; i < 13; i++)
    {
        //Writing out some debug info
        Console.WriteLine(i.ToString() + ":" + args[i]);
    }

    //<Setup>
        Microsoft.Office.Interop.MSProject.ApplicationClass msProjectApp;
        Project project;
        Thread.Sleep(1000);
        Init(args, out msProjectApp, out project); //This Includes Leveling Reset
        return;
    //</Setup>
}

private static void Init(string[] args, out Microsoft.Office.Interop.MSProject.ApplicationClass msProjectApp, out Project project)
{
    msProjectApp = new Microsoft.Office.Interop.MSProject.ApplicationClass();
    Thread.Sleep(2000);
    //msProjectApp.AppMaximize(); //Maybe Delete

    //Where args[0] is the msprojectfile.mss file location
    LoadFromMPPFile(args[0], msProjectApp, out project);
    Thread.Sleep(2000);
    project.LevelClearDates();
}

private static void LoadFromMPPFile(string location,Microsoft.Office.Interop.MSProject.ApplicationClass msProjectApp,out Project project)
{
    object missingValue = System.Reflection.Missing.Value;
    //Dies at the next row
    msProjectApp.FileOpenEx(location,
    missingValue, missingValue, missingValue, missingValue,
    missingValue, missingValue, missingValue, missingValue,
    missingValue, missingValue, PjPoolOpen.pjPoolReadOnly,
    missingValue, missingValue, missingValue, missingValue,
    missingValue);
    Thread.Sleep(1000);
    project = msProjectApp.ActiveProject;
}
