Thanks for creating a new thread. So that you can get your work done, I would recommend converting your Powerpoint presentations to other formats so you can at least view them. To do this, use the free ZamZar: Zamzar - Free online file conversion
Simply upload the file, select an end format and download it. Powerpoint presentations can be converted to:
- html – Hypertext Markup Language
- odp – OpenDocument presentation
- pdf – Portable Document Format
- png – Portable Network Graphic
- ppt – Microsoft Powerpoint Presentation
- ps – Postscript document
- swf – Macromedia Flash Format File
Choose something like .pdf, convert the document and have fun working!
