Anand,
Sorry to hear you are running into this issue. Why do you wish to un-install MyEclipse? What is your OS and version?
Here are the steps to manually un-install MyEclipse –
1. Make sure the MyEclipse Install Directory has been completely removed
2.1. Pulse Install Directory, on XP it’s under C:\Program Files in \Pulse or \Genuitec, and on Vista it’s under <USER.HOME>\AppData\Local and then under \Pulse or \Genuitec again
3. Then make sure the pulse2.locator file under <USER.HOME> is erased as well
Let me know how this works for you.
Best.
