Message: A serious program error has occurred

Version: 3.5x, 4.x, 5.x - Scientific WorkPlace & Scientific Word


On rare occasions, the program can fail. You see this message:

A serious program error has occurred. All modified documents have been saved with the extension .dmp. The program will now exit.

After the program exits, you see a second message:

The program has generated a file describing the state of your system at the time of the error: (filename.mdmp). To help us diagnose and fix the problem, please attach this file to an email message and send it to


If the program fails, it saves all open and modified documents in files of the same name with the extension .dmp, as the message indicates. After you reopen the program, open the .dmp files and check that they contain your latest changes, then save the files. The program saves the files with the original .tex file extension, and you can continue working on them as usual.

At the time of the failure, the program also generates a file containing diagnostic information that our Technical Support staff can use to determine the cause of the failure. The file has the extension .mdmp. As the second message indicates, we urge you to create an email message and attach the .mdmp file and the document in use when the failure occurred, then send the message to us at
