I can't install correctly Adobe Captivate 8, cause a message of no connection to internet appears (I am connected to internet). Even though, when I try to unistall through the control panel it doesn't let me, an Uninstall Failed message appears,  anyone knows how to uninstall it??

I've already tried Adobe Cleaner Tool, but it doesn't work, as the program is not listed as one of the proposed

Does anyone know how to uninstall it??

Thank you
