If you're talking about the flash player you'll know it's working when you try to run a swf and it works.
the problem is nothing happens after its installd jst says finish installing . i go to adobe and theres nothing there and i dont get any icon nothing runs . im i doing somthing wrong did i miss a step do i have to change a setting on my PC.
if you run something in flash just right click and it will tell you waht version is installed . If that's the version you were trying to install then it worked.
