"Access to .tif denied" Error Message for TIF Viewer in Windows 2000/XP

Hello everyone.  I have a program that is giving me fits on my LAN.  The name of this program is "eFax Messenger Plus".  You'll commonly see the free version (which I'm using) referenced as an adware-type program b/c it serves up ads as you're viewing and saving eFax documents.  So, I'm aware of that fact if anyone has experienced it in the past.  My problem with the software is hopefully a little more simple and could possibly be related to a Windows OS config.

When this program is installed on a domain user's account who is a member of the "Users" group on the local machine and a regular domain user as well, the user will receive an error message reading "Access denied to .tif" each time the program runs.  Now, if I promote the user up to being a "Power User" on the local machine (Domain memberships stay the same), the error message will disappear.

This is a successful workaround but it puts the user (and network) at a greater risk of executing spyware/viruses.  My goal is to get the user to be able to run the program as a member of the 'Users' group (aka 'Restricted Users) without this error message.

As a note, the user can successfully run the program even after receiving the error message but it is a major annoyance as it comes up with each .tif file that is opened.

From my research, I am suspecting that this error is caused by the 'Restricted User' account not having some rights to something in Windows that has to do with .tif file access rights.  It could be in the Registry, in Group Policy, could be anywhere.

Lastly, this may not even be something that can be fixed b/c of the way the eFax program calls the .tif access.  I just wanted to take a stab at it with you guys.  I will assign the maximum points value to this question and the points will be awarded for a successful fix as outlined above.

Thanks everyone!

Hello heatfan07
You have said here that >>> From my research, I am suspecting that this error is caused by the 'Restricted User' account not having some rights to something in Windows that has to do with .tif file access rights.  It could be in the Registry, in Group Policy, could be anywhere.

Then why dont you make sure if it works normally with new user account?
Also I would suggest that you try to open the .tif document with Microsoft Office Document Imaging if you have microsoft office installed on your system, or download the free tif " Irfan viewer " google it and you'll find a download link,. its free and better than using the eFax Messenger Plus.

Now Click Start --> Run and Start registry editor " Regedit.exe "
Note: Don't forget to backup your registry always before editing.

1. Navigate to the HKEY_CLASSES_ROOT\.tif subkey.
2. Double-click the Default value and change the value data from TIFImage.Document to Imaging.Document.
3. Navigate to the HKEY_CLASSES_ROOT\.tiff subkey.
4. Double-click the Default value and change the value data from TIFImage.Document to Imaging.Document.
5. Close the registry editor.

Check if this works.

If my original post was unclear, I apologize.  I am not looking for an alternative image viewer for .tif files.  I have some users on my LAN who HAVE to use eFax Messenger Plus to view and save .tif files.

I have already verified that I still experience this behavior with any user account that is a member of the 'Users' group (aka 'Restricted Users'), even a new user.

Thanks again to everyone who posts!

Try and edit the registry key as i posted above, it'll help.

Hi moh10ly,

You post actually pointed me in the right direction on this one.  I found that I could make Windows associate eFax Messenger Plus with .tif file extensions by installing it from an Admin account (either local or Domain-wide account).  Then, I have to promote the regular user up to an Admin on the local machine.  Next, I log into the user's account.  eFax Messenger Plus will prompt each user account once to run a setup process which can only be completed by a user with administrative rights (hence the temporary promotion).

Now, there is a screen that you reach during setup that requires you to check file type associations.  I have dechecked them all for this regular user masquerading as a local admin. (I left .tif checked during the real setup from the admin account).  Lastly, I complete the setup, log out from the current user, go back into the Admin account, remove the regular user from being a local admin, and then go back to the regular user's account.

Now, the regular user can open .tif files with no error message prompts!  Phew!!  That was a tough one but your mention of the File Associations in the registry got me pointed in the right direction.
