How to make the "Always use this program to open these files" enabled
.tif has no file associations and the associations box under Open With is grayed out. Attempting to associate with Microsoft Photo Editor as a majority of these are fax images created with Microsoft Fax Shared Client.
Logged in as admin on a Win2k Terminal Server running Citrix MP3. Attempted the Shift/right-click/open to no avail. Attempted to modify HKCR\.tif with various options but the program would not load so I apparently don't have the right key combination. Tried photoed and photoed\tifffile and variations of that as well.
