Dear Sir,

I have downloaded and installed the above software in my home PC and 3
servers at the work place recently.

Surprisingly I find that I could not open MS Excel 2007 and Words 2007
documents using Excel 2002 , Words 2002 or Excel 2003 readers and Word 2003
readers.

The error message display reads: €œ Unknown file format€�

May I know how to overcome this problem ?


Thanks

Low
