Resolving “MySQL Workbench has stopped working” Error Message – Workbench v5.2 Windows Event ID 1026 and 1000


– I am running Windows 7 Ultimate 64-bit.
– Installed MySQL Workbench 5.2


– Worked fine for a while, but as soon as I start the program now, I get a message box saying “MySQL Workbench has stopped working”


I checked Event Viewer and see two logs:

1. Uninstall (aka “Remove”) MySQL Workbench 5.2

2. In C:\Users\YOUR_USERNAME\AppData\Roaming\MySQL, rename “Workbench” to “Workbench_old”

3. Reinstall MySQL Workbench

4. Check out the folders in “C:\Users\YOUR_USERNAME\AppData\Roaming\MySQL”, and notice the “Workbench” folder is recreated

5. Launch MySQL Workbench and all is good!

[learn_more caption=”Extra Note”] Note: For good measure, I renamed back the folders in “C:\Users\YOUR_USERNAME\AppData\Roaming\MySQL” to test if that was the issue, and sure enough, as soon as I put the “old” folder back into place I had the same issue launching MySQL Workbench.

  1. Thanks for the tip!

    Why to go through all the hassle of un-installing and then reinstalling the application? I just renamed the original “…\Roaming\MySQL\Workbench” to something else as you stated and then created a new empty folder with the name “Workbench” manually and … it also worked for me 馃檪

  2. Parab茅ns!!!
    Funcionou perfeitamente! J谩 tinha feito de tudo!
    Muuuuuuuuuuuuito obrigado pelo post!

  3. THANKYOU!!!!

    I’m running Windows 8 and Workbench just stopped working…. trawled through hundreds of blogs and bug reports and uninstalled / re-installed / updated…. absolutely nothing worked!!!!

    Your solution actually works and has finally ended 2 days of pain!!! THANKYOU!!!!

  4. Very glad this helping folks., even now in Windows 8 world. Lloyd seems to have really been in a bind; thanks for sharing the comments…makes me feel good and justifies the time I spent creating the post! Happy Workbenching, if that’s a thing.

  5. another way to possibly resolve the issue. i noticed that the application created a file in the roaming directory called otherconnections.xml. The file contained a bunch of null values. i renamed the file and restarted the workbench and the error went away.

  6. por si a alguien le interesa, a mi me estaba fallando y no encontraba soluci贸n, lo que hice fue reparar el .net framework 4 o el 4.5.1 dependiendo la version que tengas, y con eso me funciono, reinstale mil veces el workbench pero al menos a mi la version 6.1.7 no me generaba nada dentro de roamin, aun renombrando la carpeta como se muestra arriba, pero al reparar el net framework me funciono =D, espero que a alguien le sirva, saludos.

  7. Funcion贸, pero al final de la instalaci贸n en el MySQL Installer el Instalador tuvo un ‘truene’. Es decir, una excepci贸n. Ahora si abre el Workbench… 驴No afecta que el Installer haya tronado?

  8. Tengo windows 8 y en la carpeta Roaming no se me genera nada, asi que no hay ningun archivo para renombrar鈥.Alguien Puede ayudarme con eso?

  9. fiz o procedimento, estou usando o windows 10 e nao funcionou, toda a vez que clico em salvar, aparece o erro e fecha o workbanch
