Getting exception while saving a .pptx file

Question

I have a Presentation object as follows,

using Presentation = Microsoft.Office.Interop.PowerPoint.Presentation;
Presentation pptPresentation = pptApplication.Presentations.Add(MsoTriState.msoFalse);

after some processing, at the time of saving,

pptPresentation.SaveAs(@"c:\temp\myPPT.pptx", Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsDefault, MsoTriState.msoTrue);

it's throwing an exception.

I will greatly appreciate any help with this, it's got me stumped.

Environment Details:- Windows 2008 Server(x64), .NET 3.5, IIS7

Answer 1

Finally I got the magical solution.

I just created two folders in the Windows 2008 Server

C:\Windows\SysWOW64\config\systemprofile\Desktop and C:\Windows\System32\config\systemprofile\Desktop

And after applying read permission to the folders, the ppt is getting save in the local directory of the server. Source
