Why do I receive a "Runtime Error" or segmentation violation during startup on my Windows computer in MATLAB 6.5 (R13)?
Show older comments
When I launch MATLAB I receive the following error:
Runtime Error!
Program C:\MATLAB6p5=bin=win32\matlab.exe
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
and the following log file named matlab_crash_dump.XXXX is left in my C:\temp directory:

The segmentation violation can be caused due to a corruption in either the profile of the current user or by corrupted Windows libraries. In order to determine which is the cause, try logging in as a different username and run MATLAB.
If you are able to successfully launch MATLAB under a different username:
1. Log onto the machine, as the user that is receiving the error.
2. On your desktop, click on Start > Run
3. Type "regedit" in the Open text field and click OK, this will bring up the Registry Editor
4. In the Registry Editor expand the following folders: HKEY_CURRENT_USER > Software > MathWorks > Matlab
5. Under the MATLAB key, find the folder having the same name as the version number of the MATLAB that is crashing; and delete it. This Registry key will be regenerated the next time MATLAB is started.
Click on the link below to view an image of the Registry Editor, which shows how to delete a registry key for MATLAB 6.5 (R13).
After following these steps, you should be able to launch MATLAB successfully.
If MATLAB crashes regardless of the user who is logged in, the crash may be caused by corrupted system libraries. For Windows NT, 2000, or XP, some customers have found that reinstalling Windows Service Packs have resolved the issue.
