Oh shit i thought madness day is tommorow oh god

vacation is almost over

Hey can someone help me with getting the NG player working? After I try to boot up a game it asks me to install adobe flash. After I clicked yes, nothing happened. So I went online and downloaded the flash installer, but then it wouldn't download, and just take me to the " flash end of life" page. So can somebody help me get it to work? Thanks in advance.
