I am running Windows 10 on an HP Pavilion desktop computer. Iupgraded from Windows 7. I installed Outlook 2013 before that upgrade andwas using Microsoft Word 2002 as my word processing software. Everythingworked fine before the Windows 10 up grade. Now if I try to open a fileattachment in Outlook I get told " This is a pre release version of theCompatibility Pack and can open pre-release Office 2007 files ony. Do youwant to check for a newer version of the Compatibility Pack? When Iclick on "OK" I am sent to a Web page where I get asked if I want todownload and install this new Compatibility Pack....I have done this nowsomething like over 12 times and it does not work. WHAT CAN I DO
