Description

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

Issue

- 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:

Solution

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!

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.
