I`m a win 7 pro user and i`m having the same problem. everything work fine before the latest update(except the low fps cutscene). After the update, the launcher keep showing "destiny2.exe - entry point not found" i`ve re-install both battle eye and destiny 2 several times which doesn`t solve any problem. I`m busy doing all the bounty last week just to prepare for this season, then i can`t even log in to the game, this really feel bad, hope you guys can solve this problem soon. i just want to log in and have some fun. good luck to all the guardians who are having the same problem and the dev who are trying to fix this.
