File association keeps disappearing

[Jtorres13]

Hello. I have one user who goes to a court website and opens TIFF files. The extension is .TIFF, not .TIF. When she tries to open the file, machine asks to Save the file, no option to just Open it. This is because the file type is not associated with any application. When I go to the Explorer | Tools | Folder options | File Types I see that both file types are not listed. I create a file type and associate it with the Microsoft Document Imaging (it can open multipage tiff files). So, things are working OK.

A month later, user calls me back with the same problem. I create the file types again. Now I'm getting suspicious.

A month later user calls me back with the same problem!!! She swears she's not touching anything that may cause this.

All users have permissions to change this if they wanted but they just don't know how to do it. Registry is also open to regular users. We have Windows XP SP3 with all patches. Problem started before SP3 and most patches were installed.

Any ideas? I read thread779-1187567 but there's no solution. I tried the links sugegsted in that thread.

Have a look around this area in the Registry, perhaps you can create a batch file or similar to reinforce the association at regular periods? Of course that doesn't explain why XP is not remembering the association in the first place, unless some third party program is attempting to replace the association and mucking it up somehow.

Is there any Fax software that could be causing your problems with .tiff associations?

Thank you for answering. The faxing software is a network printer that calls a Kyocera software. Basically users chose to "print" to the network fax. But that Microsoft Document Imaging is installed with Office 2003.

I will test to see if there's a relation.

Thanks for the links. I will try them and post my results.
