Current generation (27") iMac running OS 10.8.5. Can't install Flash Player. Download gets to 50%, then quits with "General Installation Error." Reproducible. Uninstalled v. 11 of Flash using Adobe's Uninstall program. Followed all the suggestions on Adobe's trouble shooting page (helpx.adobe.com/flash-player/....) Still no success, or even improvement... 50% download, then that's all she wrote.
Any ideas, Adobe? Hard to believe my situation is unique.
