Creating DUMP files in MapInfo Pro

Products affected: MapInfo Pro™
Locating the MapInfo Pro Log File (minidump file)
When MapInfo Pro closes unexpectedly, it generates a binary log file that is referred to as a minidump file. Technical Support uses this file to investigate and fix the issue that caused the unexpected closure. Depending on what occurred, providing sample data or access to the data may not be necessary.

MapInfo Pro saves the minidump file in the Windows %temp% folder under a subfolder called MIPRO. The %temp% folder is set by default to:
To browse directly to this folder location:
  1. From the Start menu select Run.
  2. The Run dialog box opens.
  3. In the Open text box, type %temp%/MIPRO.
The minidump file has a date and time stamp in its name in the format yyyy_mm_dd_hh_mn_ss.dmp. Where:
  • yyyy - year
  • mm - month
  • dd - day
  • hh - hour
  • mn - minute
  • ss: seconds
When reporting an issue to a Technical Support associate, send this file with your report. Depending on what the issue is, this file will speed up the response time to the issue.
Users may be asked to set an environment variable to generate a minidump file that has more information in it. This helps Tech Support determine why MapInfo Pro closes unexpectedly and how to fix the issue.
To include more details in the minidump file, by setting the MI_FULLDUMP environment variable:
  1. Select Start > Run.
  2. In the Run dialog box, type Control Panel.
  3. In the Control Panel, select System and then Advanced System Settings
  4. In the System Properties dialog box, select the Advanced tab and then click Environment Variables.
The Environment Variable dialog box opens.
  1. In the User variables panel, click New.
  2. In the New User Variable dialog box, do the following:
    • In the Variable name field, type MI_FULLDUMP.
    • In the Variable value field, type the value 1.
  3. Click OK to close the dialog boxes and save the new variable.
If MapInfo Pro is running, then stop and restart it now to apply the new system variable. The minidump file could be large; a typical size would be between 500 MB and 1 GB. Compressing the file may be necessary (using a compression tool, such as 7ZIP) before sending it to a Technical Support associate, or arranging the file to be available for download.
