I have installed latest free version of zend studio and it got expired. I can not see any uninstall program along with it. How can I uninstall it from ubuntu 11.10 ?
it depends how you installed it.
if it was a .deb package, you can remove it by :
sudo apt-get remove --purge package-name
otherwise you could find something in this folder :
cd /usr/local/Zend/ZendStudio-7.2.0\Uninstall\ Zend\ Studio\ -\ 7.2.0/
sudo sh ./Uninstall_Zend_Studio_-_7.2.0
