PowerPoint can't read the outline from ...ppsx. No text converteris installed for this file type."

[Ant]

Hello.

I am unable to open a downloaded PPSX file
(http://199.91.153.49/ou38vi2jw3xg/5lvmpmxbtbbifin/A+Survey+on+Wireless+Security.ppsx
from
http://www.mediafire.com/download/5lvmpmxbtbbifin/A+Survey+on+Wireless+Security.ppsx
) in my old updated Office 2000 SR3 with its Office 2007 Converter Pack
addons in old, updated Windows XP Pro. SP3. I get "PowerPoint can't read
the outline from E:\dl\A Survey on Wireless Security.ppsx. No text
converter is installed for this file type." error. This only happens if
I open in PowerPoint's file's open menu. I can open it fullscreen from
Windows Explorer, but I don't want to use that.

Thank you in advance.
