Download a SlideShare presentation as a PowerPoint file

The SlideShare online presentation feature you are looking for is called Zipcast. Zipcast has both a free version and a paid version. The paid version of Zipcast is included as a feature in the paid SlideShare PRO Account. The features of the free version of Zipcast are:

• Unlimited public meetings (ad-supported)
• Video & chat included

SlideShare Zipcast works in any modern browser. You can find instructions for how to start a web meeting in Zipcast by visiting the link mentioned previously which links to a slide presentation called Introducing Zipcast.

I've had a response from Slideshare/LinkedIn support for this issue - spotted the thread when looking for alternate solutions.

Thank you for your email and I am sorry for any inconvenience this may have caused. We're always looking for ways to improve the SlideShare experience for our members. This sometimes means removing features that aren’t heavily used to invest in others that offer greater value. Please know we continuously evaluate how features and products are used, and make adjustments accordingly to focus our resources on providing the most value to our members.

As a result, we have removed the ability to re-upload documents to SlideShare. As a workaround, you can upload a new file to SlideShare and delete the current one. Please be aware that this means we will not be able to transfer any views/likes/URL's to the new presentation. Again, I apologize for the inconvenience and we greatly appreciate your feedback. We have documented the issue in order to track additional reports of the problem and for consideration to be addressed in a future release. If there's anything else I can help you with, please don't hesitate to let me know.

Or put in other terms, "we don't give a damn". I can understand changes being made, but this seems arbitrary and no notice has been given.

I'd just uploaded a draft presentation for a talk I'm giving later in the week, so I can get some printing done and have the right URL ... except now that URL is incorrect and of course because the printing has already been completed, I'm going to have to pay for the whole print run again.
