I am at vacations, Yoga, that always means _less_ free time.
Also, I am always in my chats. It's about you that you don't like them. :P
Speaking about your problem - what your Task Manager says? Is FlashPlayer installer listed here at all? If it is, it means that installation process itself came wrong. If it isn't - maybe your antivirus or something went wrong?
You always can wait for the _next_ installer, right?
