What is this and what can I do?
Thank you
FL

FL,

You seem to be facing DLTK issue. Could you do the following -
1. Open MyEclipse IDE, from menu options click on Help > MyEclipse Configuration Center
2. Open Dashboard tab
3. Uncheck the feature "MyEclipse IE JavaScript Debugger (for Windows only)" and click on [Apply 1 change] under "Pending Changes" and follow the wizard till completion
4. When prompted choose to restart the IDE

Let me know how this works for you?

Wow, thank you for the quick reply.
I done what you wrote and it is working now, PHPEclipse installed successfully.
Thank you, FL

FL,

Good to hear you are all set. Let me know if you have any other queries.
