I tried updating Adobe Flash Player, on two different, Windows Vista, 32-bit, laptop computers, to go from version 24.0.0.something, to 22.214.171.124.
Both computers, the attempted updating failed to install.
One computer had NPAPI plugin and Active X forms of flash player. .Browsers are Firefox, IE 9, portable Slimjet
Other computer has only ActiveX form of flash player. Browsers are IE 9 browser, Google Chrome, and portable Slimjet browsers
First used Control Panel, opened Flash Player control, Update tab, then Check For Updates, followed typical displayed instructions.
But install failed.
I used the adobe site after the first failures. I downloaded offline installer and tried that, but still install failed.
What's happening? How do I find out? What should be done next? Should I download the uninstallers for flash player?
