Can I uninstall Java Runtime Environment 32 without any issues? I have Java 7 update 51 and Java 7 update 51 (64-bit) both installed. I want to uninstall the 32-bit version. I am developing in Java, using the 64-bit JDK.
Per java.com, you only need the 64bit JRE if you plan on running a 64bit browser. Windows x64 systems by default have seperate 32 and 64bit versions of IE, so if you plan to use the x64 option (x86 is default), you need a 64bit plugin and JRE.
If you plan to run Firefox/chrome/whatever-other-x86-browser, just use the 32bit.
if you are getting a JDK for development determine what version is appropriate for your IDE or other development tools, and use it.
