title: Your port 80 is not actually used
body: <p>I have been using wamp 2.0 version for about a year. After which I decided to upgrade to a newer version of 2.2 or 2.5. I uninstalled the 2.0 version and copied all my files to another location. After the new version installation apache did not startup. I test the port 80 and it displays <strong>"Your port 80 is not actually used"</strong>. I have tried as many as possible installation and deletion of the wamp folder before installing another version. But after series of test the 2.0 version is still working perfectly when installed again, but I insists on using the newer version, just to get the new features to be used. Any help will be appreciated. I have google searched for over 24 hours now. Fellow programmer please help me. Thanks in advance </p>
