LM7, do you know that those registry fixes have been updated to accommodate Office 2010? They were previously only valid up to Office 2007, IIRC.
In Office 2010 Microsoft added the "Microsoft Office Software Protection Platform Service", mainly to take Office files out of the situations/locations where macro-type worms and the like can be easily planted. One of its changes was to disallow the opening of Office files in Internet Explorer, which is how Ultra Recall accesses them as it uses IE for its internal browser. I know that when Office 2010 was initially released those registry keys did not fix the issue and in some cases caused problems with IE7 (or it might have been IE8?) and Office 2010. Then when IE 9 was released and caused problems for all or most apps that used IE for their internal browsers, users had to uninstall IE9, which automatically dropped users back to IE8 (IF they used the Office Uninstall link in the Start Menu). The registry keys to be added look the same as they were for Office 2007.
I did search around for a fix to allow opening Office files in IE, but all I could find was the opposite - ways to prevent that! If those registry fixes work for Office 2010 I'll make the changes immediately! I prefer doing it manually so I can backup each key I remove before making any changes.
Thanks!
Jim
