I own a Macbook osx 10.5.8. I was trying to upgrade to a new version of Adobe Flash Player. I was prompted to first uninstall the old player and I did so. When I tried to download the new player I was told that my system would not support it. I have been unable to reinstall the old system. What am i doing wrong?
10.5.8 was the last of the Universal Binary builds (PPC or Intel) of OS 10. As such, Adobe stopped development of Flash Player that was compatible with PPC versions once Leopard (10.6) was released.

If you're running a Power PC Mac, you're going to find it increasingly difficult to update software, and access websites that rely on "Intel only" versions of things like Flash Player.
