While trying to solve my browser slowdown, I was given the advice that my Flash may be corrupted,
the slow pages all had flash. My computer would not update flash at the time, the download screen popped up, and I would click to run, also tired to save to desktop.
Eventually, I uninstalled flash and decided to try to start over.
Now, I have the same problem, it won't install, and I am stuck without Flash at all.
The instructions on the troubleshooting guide were way over my head!
