How can I upgrade from OS 10.7.5 to a version which supports Zoom?

If you have tried to install Yosemite, El Capitan or macOS Sierra the download works in a different way.
First of all you download Install MacOSX.dmg (Yosemite or El Capitan), or InstallOS.dmg (Sierra)
then you double-click on the .dmg to get InstallmacOSX.pkg or InstallOS.pkg.
double-click on the .pkg and you will see an installation window.
This installation window does not actually install the OS but creates an installer app in your Applications folder.
Have a look for Install OS X Yosemite.app or Install OS X El Capitan.app or Install macOS .app.
It is this installer app that you use to install the OS of your choice.

Try reinstalling this in Safe Mode, but not using Firefox...

Safe Boot, (holding Shift key down at startup).
Sorry, this does not work. OS 10.8 or newer is required. Where can I get 10.8???
Try upgrading to El Capitan first.
Yes.. this answer is true if the machine originally has El Capitan.
I have an older MacBook Pro (Late 2011) with OS 10.7.5. I downloaded Yosemite as well as Sierra and tried an update. The installed reported a successfull installation, but the running system remains to be OS 10.7.5. What can I do?
