- 05 Sep 2016 12:55 #185552 So I am having trouble with the launcher telling me that I need to be running a 64 bit version of java. So I looked around on the forums to see if other people have had this issue. What I saw to do was to delete all the 32 bit versions I had, so I did. Then I downloaded java in 64 bit browser, and yet it still says that my version is 32 bit. Any help would be much appreciated!
