Today Macromedia has released Flash Player 18.104.22.168. If you had visited a page containing a Flash application maybe you’d received a message that suggested you to update the player. And, inevitably, you won’t be able to do it! This did occur because the Flash Player installer is buggy and the installation process will halt with an error…
After half an hour surfing the web for a solution, I “put together” some steps that helped me to finally update the player. First, you have to remove the current version. To do this, download the proper uninstaller:
After this, close the browser and open the .dmg file that you downloaded, the click on the icon of the uninstallation program and finally confirm to open it (this is an app downloaded from internet, so by default the system refuses to open it). After Flash Player has been removed, open the Finder and check that in “Macintosh HD/Library/Internet Plugins” the Flash plugin isn’t present. If yes, remove it. Then, check that in “Macintosh HD/Library/Application Support/Flash Player” you don’t have a folder named “Flash Plugin Installer“. If yes, remove it. Now, empty the trash then reboot the system. Now download the Flash Player offline installer:
Close your browser, click on the .dmg file you downloaded then click on the installation program and confirm to open it (like before, this app has been downloaded from internet, so by default the system refuses to open it). If you’re asked to choose for a version, make the proper choice: NPAPI for Safari/Firefox, and PPAPI for Opera/Chrome. After the installation, restart the browser and check at this page if the Flash Player plugin is working correctly: if you see an animation inside the window at the middle of the page, everything is OK.
