For the past few hours I have been trying to install 64 bit java after I uninstalled 32 bit java. I went to the control panel, went to java, and uninstalled it. I tried to install 64 bit java and got error 1603 and now I can't even go back to 32 bit. I've tried multiple cleaners, tried looking on Java's site, deleted all java items in C:, looked all over the internet, and I still have not solved this. Are there any other methods that I have not tried?
