How can I hyperlink to PowerPoint so that the PP plays instead of opening in Design mode

The pps / ppsx still open in design mode after setting the custom MIME type.

 I have just discovered a workaround that in fact works!!!!!
What I have done is create a shortcut to the pps on the server.

So, let's say I have "myPowerPoint.pps", I then create a shortcut "myPowerPoint.pps.lnk"
Then on the web page I hyperlink to the .lnk file.

When the user clicks on the hyperlink the powerpoint will open in slideshow mode.


OK, so this works, but I am very frsutrated that it has taken so long to do something that should be easy.
Whilst I accept that there are security issues with opening a pps(x), the fact that this is for a company intranet and not the WWW, there should be some oeasy way to force the pps(x) to play without having the resort to .lnk or registry edits on all users machines.

please try this:

In IIS Administrative Console snap-in, right-click the specific Web server where the .pps file is located, and then click Properties.
Click the HTTP Headers tab.
Click the File Types button.
Click New Type.
In the Extension box, type .pps, and then in the Content type (MIME) box, type application/vnd.ms-pps.
Click OK, and then restart IIS.

Now try opening your PPS file from the link and let us know if it still opens in edit mode.

Ok I will download this and try, meanwhile I have one more thought.

1. Save the file as Slide Show (extension ppsx as you did before) and copy that in your web application folder.
2. Open this file in your application using the following command:

System.Diagnostics.Process.Start(@"C:\WebApplication1\DSE desk_worksurface_work env_routine 2010.ppsx");

I have uploaded a couple of pages from 1 of the pptx's that I am trying to publish to our intranet site.
When you open the pptx, on the first slide you will see text inside a dark blue box. When saved as html, the text does not fit in the blue box.

This is just 1 example of many pptx's that I want to publish.
I did not create the original pptx's and I am thinking that maybe they were created incorrectly? If this is the case, then I don't think that the author will want to re-do all of the pptx's.

Thanks for your suggestion Javeed....

I have tried that method before and have even tried again, but when viewed in a browser (IE8) it looks absolutely terrible. Graphical elements are all over the place, text looks terrible, boxes are misaligned.

So, I'm afraid that I cannot mark your answer as accepted.

What I need is to be able to make a number of complex pptx's available on an intranet site. When a user clicks on the hyperlink to the presentation they should see the slideshow exactly as I see it when running a ppsx from my laptop.

The problem with the suggested solution is that the result looks nothing like the ppsx.
