Setting a New App to Open a Certain File Type

[PaulG]

I would like to get Photoshop to open my .TIF files.
Another app is now set to handle these. But when I go
into Control Panel>Folder Options>File Types and make the
change, Photoshop opens OK (as the chosen application),
but the chosen .TIF file fails to load in it.

Can someone tell me where I'm going wrong?

Thanks!

Right-click any TIF file and select "Open with". Choose Photoshop from
the list or via the "Browse" button. Make sure that the "Always use
this application..." option is activated and click OK.

Thanks, but I've tried that. Apparently an entry is
missing from my Registry (a %1 at the end of the Photoshop
key), that keeps re-assignment from happening. Anyone
know how to fix THAT problem?

Find the entry in the Registry. As far as I know Photoshop uses PSP as
the extension for it own files. So go to HKEY_CLASSES_ROOT\*.PSP and
check the value for the (Default) entry here. This should lead you to
another HKEY_CLASSES_ROOT entry in the Registry where you should find
subkeys shell\open\command. The latter should contain an entry for
Photoshop's EXE file. Make sure that
"%1"
(with the quotes) is in the command-line.
