Can't get .pptx files to open

[Michelle]

Hello. I have a problem.
I have microsoft office 2007 on my vista laptop..and for some reason, I can
create powerpoints with the .pptx ending and open them, but when I open
powerpoints with the ending .pptx that are from other computers (I am a
teaching assistant), they will not open and just extrat as a zip file.

I also have the plugin to take office 2007 on my 2003 edition, but it still
wont let me open these files. Can anyone help? I dont know whats wrong!!

Thanks,
Michelle

Hi Michelle,

how do you exchange PowerPoint files with others? Via FTP or internet? We
had a similar problem recently: Our webmaster uploaded PPTX-files and when
people downloaded them, they got ZIP-files. Renaming them from ZIP to PPTX
solved the problem.

The reason is, that server software sometimes does not "understand" this new
file format.

What else can you try:
- Do not open the files with a double-click in Windows Explorer, but with
Office-Button - Open from PowerPoint.
- Have people zip the PPTX-files before uploading/sending.

Best regards,
Ute
