can't open the powerpoint 2003 files using powerpoint 2003. file convertor for office 2007 was already installed. error 'powerpoint can't open the type of file represented by .. C:\xxxx\eee\.ppt'
when use powerpoint viewer 2003 to open, it gives 'powerpoint viewer cannot open the file 'eee.ppt' because the file is not a powerpoint file.
when use powerpoint viewer 2007 to open, it also gives the same error as using powerpoint viewer 2003
You should probably ask in the Microsoft Office forums on the Microsoft web sight.
