After following instructions I did unistall Office 2010, used the cleanning programs, went to the Register and remove all instances of Microsoft Office going back to Office 12, 13, 14 amd 15. I did remove all Microsoft Office folders and files and still I have the same problem.

I guess the solution I have is to wait for Office 365 final version and also WIndows 8 as I don't seem to have any other alternatives at present. If somebody has any ideas please let me know. I can see the files in Outlook using Preview as that program is working fine. Frank
