Error with downloading flash player with mac

Every time I try to download the new flash player the download starts and than says I need to close safari and chrome to continue. After I close the applications it downloads a little more than tells me the same thing. But Safari and Chrome have already been closed so I press retry again and it will download a little bit more than do the same thing. I keep pressing retry till it gets to about 98% downloaded and than gives me an error that it can't be downloaded at this time.
