PowerPoint is installed on the server. I have done as you have said and got the following error: Object reference not set to an instance of an object.

Just checking - the last time you asked this question you did not confirm that you had PowerPoint installed on the server. Did you clear up that problem? With the
COMException- check theInnerExceptionproperty to see if you can get more details on the specific nature of the problem. You would do this by putting your code in atry/catchblock and outputting theMessageor ToString() of theInnerException(assuming there is one) so you can see the details.
