I am trying to install Flash 12 on a Mac running OS 10.9.1
Main browser Firefox.
I've tried several times this year but always get the same error. The progress bar on the installer stops and the error message: "Error: Unable to proceed with the installation"
Today I tried a clean install. Downloade the uninstaller, removed Flash, restarted computer, and then ran installer. Same result.

Thank you for your help.
Thank you very much. The installer link you provided worked perfectly.
