Unable to uninstall Applications Manager

I am unable to uninstall Applicaitons Manager from my m/c. These are the steps I did.
1. I tried to uninstall from Start/Programs/ManageEngine Applications Manager7/Uninstall Applications Manager.
-> Then it asked me to stop Applications Manager and do uninstall,
2. Now I stopped it and tried then it says.
"Directory Error! Uninstallation cannot proceed, the C:\Program Files\InstallShield Installation Information\{e6aea16f-0377-42b0-b4eb-7fa3dbbfdfaf} directory exists!. Check if it is empty and delete it if it is. Then retry the uninstall.

-> Now I removed this directory and its contents and tried again, Now I got below message.

"Directory Error! Unable to restore the uninstall directory to its old location"

Can any one suggest me how to overcome this problem and complete my uninstallation.

Thanks
Praveen
