Right now Windows Picture/Fax viewer is the default program for .tiff/.tif files.  I'd like to make this change to MS Document Imaging (which is installed) and need to do this preferably via registry edits.

Take a look in:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\

and the sub-key of that is the extension you reassigned. Under that there will be the UserChoice and OpenWithList sub-keys which will contain your redefinition.

Perhaps not as elegant as doing through the Registry, but a simple method would be Control Panel|Default Programs|"Associate a File Type or Protocol with a Program".

Yes, that will work fine but I need to roll this change out in an automated fashion to multiple workstations.

changing as required for .tif and MS Document Imaging

Or
go to HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.tif\OpenWithProgids  same for .tiff

If you are confused by now, try this

http://www.ehow.com/how_6872470_change-file-association-regedit.html

I am showing my ignorance, but I think I would first try the manual method (see http:#a39290504 ) on one PC, see what the entries in the Registry look like, and then you can disperse that setting to the other users.

Hi drawdef,
I used the normal file association technique in my file manager to make MODI (Microsoft Office Document Imaging) the default for TIF files. Here are the resulting registry items in my W7/64-bit system:

(1) HKEY_CLASSES_ROOT\MSPaper.Document\shell\Open\command

(Default), REG_SZ, "C:\Program Files (x86)\Common Files\Microsoft Shared\MODI\12.0\MSPVIEW.EXE" "%1"

(2) HKEY_CLASSES_ROOT\MSPaper.Document\shell\Print\command

(Default), REG_SZ, "C:\Program Files (x86)\Common Files\Microsoft Shared\MODI\12.0\MSPVIEW.EXE" /p "%1"

(3) HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.tif\OpenWithList

a, REG_SZ, MSPVIEW.EXE

(Of course, "a" could be b, c, d, whatever.)

(4) HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\EXTENSIONS

tif, REG_SZ, "C:\Program Files (x86)\Common Files\Microsoft Shared\MODI\12.0\MSPVIEW.EXE" ^.tif

(5) HKEY_LOCAL_MACHINE\SOFTWARE\Classes\MSPaper.Document\shell\Open\command

(Default), REG_SZ, "C:\Program Files (x86)\Common Files\Microsoft Shared\MODI\12.0\MSPVIEW.EXE" "%1"

(6) HKEY_LOCAL_MACHINE\SOFTWARE\Classes\MSPaper.Document\shell\Print\command

(Default), REG_SZ, "C:\Program Files (x86)\Common Files\Microsoft Shared\MODI\12.0\MSPVIEW.EXE" /p "%1"

Regards, Joe
