I see the below messages when I try to open certain .ppt and .pptx files, got from a client through "4Shared.com" file sharing website without zipping the files.
Error Message for .ppt: "PowerPoint can't open the type of file represented by [FILENAME]" or "No text converter is installed for this file type".
Error Message for .pptx:"The document [Filename] caused a serious error the last time it was opened. Would you like to continue opening it?"
If I click YES button.... I get the below error message
"PowerPoint found unreadable contents in [filename]. Do you want to recover the contents of this presentation? If you trust the source of this presentation, click yes."
Then a progress spinning wheel spins for the entire day.
