XCLN: Unable to Open DCX (FAX) Attachments

• Microsoft Exchange Windows NT client, version 4.0
• Microsoft Exchange Windows 95 client, version 4.0

SYMPTOMS

When double-clicking on an attachment with a file extension of DCX (Fax document), the following error message may occur:

   Program Not Found
   Windows cannot find Faxview.exe.
   This program is needed for opening files of type 'DCX Image Document'."

CAUSE

This occurs because the Microsoft Exchange client is not installing Faxview.exe on computers running Windows NT 4.0, but is associating DCX file types to Faxview.exe. The Microsoft Exchange client Setup does not install Faxview because Windows 95 OSR2 and Windows NT 4.0 use the Imaging Accessory (Wangimg.exe) in place of the Faxviewer Accessory.

WORKAROUND

To work around this problem:

• Associate files with a DCX extension with the appropriate fax viewing utility.

Windows 95 OSR2 and Windows NT 4.0 do not have the Faxviewer Accessory available as an installable accessory. Windows 95 OSR2 and Windows NT 4.0 use the Imaging Accessory (Wangimg.exe) in place of the Faxviewer Accessory. If Wangimg.exe is available, faxes can be viewed by associating DCX files with the Wangimg.exe program while using Windows 95 OSR2 and Windows NT 4.0. Wangimg.exe is located in the Program Files\Windows NT\Accessories\ImageVue\ directory on Windows NT 4.0, and in the <Win95root> directory on Windows 95 OSR2. If Wangimg.exe is not available, the Imaging Accessory will need to be installed from Windows 95 OSR2 or Windows NT 4.0 Setup before DCX files can be associated with Wangimg.exe.

MORE INFORMATION

When the error is displayed, you will have the opportunity select the correct location of Faxview.exe by clicking Locate in the error message dialog box.

If you are using Windows 95 and have the Windows 95 Accessory Faxviewer installed you can locate the program Faxview.exe in the <Win95root> directory. If you are using Windows 95 and do not have the Windows 95 Accessory Faxviewer installed you will not be able to locate the file Faxview.exe unless it has been installed as part of another application. Windows NT 4.0 does not use the Accessory Faxviewer and you will not be able to locate the file Faxview.exe under Windows NT 4.0 unless it has been installed as part of another application.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
