I am using Windows XP-SP3 and Fax Console for sending fax through modem. The problem is that I cannot view the fax I have send. When I try to do so following message comes
"Need a default VIEWER for fax documents (.tif files)."

So please help to reinstall this .tif file

In Explorer, right click any tif file and from the menu:

Open with...
Choose Program...
select Windows Picture And Fax Viewer.
Check the box for "ALWAYS use the selected program to open this type of file"
Click OK
Thanx, I use following METHOD to resolve this problem from Microsoft

To resolve this issue, reassociate .tif files with Windows Picture and Fax Viewer. To do this, follow these steps:
Click Start, click RUN, type MSPaint in the Open box, and then click OK.
In Microsoft Paint, click Save As on the File menu.
In the Save as type box, click TIFF (*.TIF;*.TIFF).
In the Name box, type Test.
In the shortcuts LIST on the left side of the Save As dialog box, click Desktop, and then click Save to save the Test.tif file to the Desktop.
Close Microsoft Paint.
Press and then hold the SHIFT key, and at the same time right-click the new Test.tif file on the Desktop.
In the shortcut list that appears, point to Open With, and then click Choose Program.
In the Programs list, click Windows Picture and Fax Viewer.
Click to select the Always use the selected program to open this kind of file check box, and then click OK.Dias version was shorter...For speed and features, IrfanView is great for this job.

Even shorter!
