Particularly relevant excerpt: "Users should download 64-bit Java software, if they are running 64-bit IE. For downloading 64-bit Java click 64-bit manual download " The only off-line installer, as far as I can tell, has only installed the 32-bit runtime. Then we're back at square one! Am I missing something or going nuts?
Try installing the 32 bit version of Java 6. This works for version Install4J 4.0.5. Should fire right up, or allow you to re-run the installer. Any newer version or the 64-bit version of 6 will fail, complaining that the java.exe is damaged.
can u tell me how to download openjdk 8 as tcs codevita needs java 8 The best way to do this is to use the builds from adoptopenjdk. They're very high quality and come in multiple variants for Windows ranging from zip files to MSI installers. Dead simple to install JDK 8, 11 or 15.
The Answer by Stephen C is correct, and important. Oracle no longer intends for end-users to be installing a JRE or a JDK. Java Applets in a browser and Java Web Start app delivery are both being phased out, leaving the end-user with no need for a JRE. Java-based apps are expected to bundle their own Java implementation. The only folks consciously installing a JDK will be developers & server ...
The difference is that Java binaries compiled as x86 (32-bit) or x64 (64-bit) applications respectively. On a 64-bit Windows you can use either version, since x86 will run in WOW64 mode. On a 32-bit Windows you should use only x86 obviously. For a Linux you should select appropriate type x86 for 32-bit OS, and x64 for 64-bit OS.
Download latest version of JDK from Oracle (for example jdk-7u7-windows-x64.exe) Download and install 7-Zip (or download 7-Zip portable version if you are not administrator) With 7-Zip extract all the files from jdk-XuXX-windows-x64.exe into the directory C:\JDK Execute the following commands in cmd.exe: cd C:\JDK\.rsrc\1033\JAVA_CAB10 extrac32 111
So you're looking for the installer that would be the same as if you went to Oracle and downloaded the jre-8u202-windows-x64.exe? What is your OS and are you looking for 64-bit or 32-bit?
3 Installing java for casual java developers has always been something of a minefield. E.g. do we need SE or EE edition for say STS/Grails, do we need the SDK or JDK? I am pretty sure I need the JDK 1.7 for EE edition. The question is, how do I get the JDK without the bloated SDK?
If like me you do not have admin rights to install 64-bit Java, just open 32-bit R and it should work ok on your 64 bit PC as part of the problem seems to be the rJava library function calls embedded Java functions/routines, which may only have being designed for 32-bit interface with Excel/Windows and possibly too large a task at the time to change everything.
