Access Denied for Powerpoint

[Manoj Pandole]

Hi,

I am trying to create a Powerpoint object to do some
processing on a Powerpoint presentation on the web server.
But i am not being able to access the application. While
creating the powerpoint object the error show is

System.UnauthorizedAccessException: Access is denied

Although i have granted access rights to the ASPNET user
for accessing the application, even then the same error is
shown. Please help out on this.

Regards,
Manoj Pandole
