After the tip on Excel and Word, we are going to do the same for Microsoft Powerpoint.
If you are using
Microsoft.Office.Interop.PowerPoint for Powerpoint related operations in your application, then you must check if Powerpoint is installed in the client machine or not. This tip gives you that trick.
This little piece of code is a result of the research after the comment by Marco Bertschi on my previous tip (How to Check Whether Excel is Installed in the System or Not). Thanks a lot Marco.
Nice one, Tadit - It might be even improvable by providing information what the ProgID for the other office applications are (Word etc., but maybe even Visio or MS Project).
Using the Code
We will use the
Type class and its method
Type.GetTypeFromProgID Method (String).
Gets the type associated with the specified program identifier (
null if an error is encountered while loading the Type.
The type associated with the specified
progID is a valid entry in the registry and a type is associated with it; otherwise,
For Powerpoint, the
Powerpoint.Application. So, the below code is used to check whether Powerpoint is installed or not.
Type officeType = Type.GetTypeFromProgID("Powerpoint.Application");
if (officeType == null)
