Problem with using PowerPoint 2003 ins ASP.NET

[Marc Eggenberger]

Hi there.

I have an webapp (asp.net) which should use powerpoint to create a
presentation and then send that presentation to the user.

I'm using VS2003 and Office2003 (project req.).

The webapp runs find but when I try to open powerpoint in my asp.net
code I get an error

COM object with CLSID {91493441-5A91-11CF-8700-00AA0060263B} is either
not valid or not registered.

The Code is at end.
The code runs fine with an Windowsapp.
I have set the Copy Local in the References of the dll's to true so the
Interop dll's are there.

What am I doing wrong here?



code:

try
{
//Oeffne PowerPoint
PowerPoint.Appl ication objApp;
PowerPoint.Pres entations objPresSet;
PowerPoint._Pre sentation objPres;
PowerPoint.Slid es objSlides;
PowerPoint._Sli de objSlide;
PowerPoint.Text Range objTextRng;
Graph.Chart objChartPP;

//Wegen Bug Q320369

System.Threadin g.Thread.Curren tThread.Current Culture =
System.Globaliz ation.CultureIn fo.CreateSpecif icCulture("en-US");

objApp = new PowerPoint.Appl ication();
objApp.Visible =
Microsoft.Offic e.Core.MsoTriSt ate.msoTrue;
objPresSet = objApp.Presenta tions;
objPres = objPresSet.Open (".\\Vorlage n
\\pp1.ppt", Microsoft.Offic e.Core.MsoTriSt ate.msoFalse,
Microsoft.Offic e.Core.MsoTriSt ate.msoTrue,
Microsoft.Offic e.Core.MsoTriSt ate.msoTrue);
objSlides = objPres.Slides;

}
catch(Exception fehler)
{
System.Diagnost ics.Debug.Write Line("Fehler:
" + fehler.Message) ;
}
