How to open a remote ppt file by Microsoft.Office.Interop.PowerPoint?

Question

Hi all

I want to run a ppt file using c#, 32 bit Os,  windows 7. 

Part of the code is as follows:

            //Create a new presentation based on a template.
            objApp = new PowerPoint.Application();
            objApp.Visible = MsoTriState.msoTrue;
            objPresSet = objApp.Presentations;
            string strPath = @"\\192.168.31.164\isoftShare\123.ppt";
            objPres = objPresSet.Open(strPath, MsoTriState.msoFalse, MsoTriState.msoTrue, MsoTriState.msoFalse);
            objSlides = objPres.Slides;

            //Run the Slide
            objSSS = objPres.SlideShowSettings;
            objSSS.Run();

            //Wait for the slide show to end.
            objSSWs = objApp.SlideShowWindows;
            while (objSSWs.Count >= 1) System.Threading.Thread.Sleep(100);

Here if the ppt file path (strPath) is the local file like "C:\123.ppt" then is no problem, but if the file path is a network path like "\\192.168.31.164\share\123.ppt" When I run my application COMException (0x80004005): PowerPoint could not open the file.

if i open the "\\192.168.31.164\share\123.ppt" file manually by the Office PowerPoint 2007, it also work. but why use C# can't?

I did a lot of googling but problem could not be resolved.

Please help
