This might sound really silly, but what about source code that I might receive from other sources (written/precompiled in a 32 bit environment) - would I have any problems handling it? What if I install Chrome 64 bit instead? Since I would be running only 64 bit browsers on my 64 bit machine I suspect I would then only need JRE or JDK 64 bit and Eclipse 64 bit. What would be your suggestion in this case? I need to install Eclipse Epsilon (Eugenia, Xtext) for my current coursework and it only requires JRE and not JDK. Am I right then in my understanding that Eclipse should be the same bit flavor as the JDK (if installed on the machine) or as the JRE otherwise? I've even read somewhere that I won't even need the JRE if I install the JDK, since it comes with several JREs. But I've read in another post that the JRE just runs the bytecode and it doesn't matter if it was generated by a 32 or 64 bit compiler - it will run it correctly anyway. The conclusion was that I should install the bit flavor of Eclipse corresponding to the JRE version I have on my machine. What if I install JDK 64 bit? Should I go for 64 bit with Eclipse also in that case? Here Java and Eclipse - 32 vs. Now I want to install Eclipse Epsilon and I am unsure if I should go for the 32 or the 64 bit version.ĭo I have to go with 32 bit because I have JRE 32 bit installed? I also have 64 bit IE on my machine, but I hardly ever use it, so I didn't do an additional install of the 64 bit JRE, as suggested here: I suspect this was because I was running 32 bit Chrome and from what I understand it is important that the JRE version corresponds to the flavor of the browser you are using (bit wise). This is the version I was recommended when I went to the download page for the first time. I currently have the latest JRE 32 bit installed on my 64 bit machine. I know similar questions have been asked before, but I am still unsure what I should do.
