I have a Powerpoint presentation that I convert to PDF and send out to people as a sales tool.

The presentation has 500 links to a website where people pull information on products, it opens a window.

I need to convert the 500 hyperlinks to point at another website (I need to change a phrase in the each hyperlink from site=17 to site=20. Does anyone know how to do a mass edit? INdivudally editing each hyperlink is a real challenge, bearing in mind I need to do this four times (= 2000 manual changes !)

I have tried editing both the Powerpoint andthe PDF file. If I open the pdf or powerslide file in notepad I can perform a search and replace but the both files won't open in adobe reader or PowerPoint after I save it. Does anybody have any other suggestion ?

Many thanks.
