How to install a (portable) JDK in Windows without admin rights 2014--11-22 Nick Russler It recently happened to me that I was stuck at work on a Windows installation without access to admin privileges.

1. Install 7zip Without Admin Windows 7

I like how Chrome/Firefox's installers approaches the issue: Asks you for admin access and if you can't provide it it will ask you to install it as regular used. From my experience, installing those without admin right does not impede the functionality one bit.

How can I install the Java Development Kit without administrator rights?

Here is a workaround to install java without admin privileges or without administrator password. For this you need cygwin installed which does not require admin privileges.In the utils make sure you select cabextract.exe to install it.

Fireup cygwin bash shell.

Type cabextract jdk1.6.exe <-- jdk file name

this will extract all the files into the current directory.

Move tools.zip to a new directory and unzip it using cygwin or windows explorer. This will be your java directory.

Hint: Try to subsitite 7zip instead of cabextract and cygwin. If it works it will be much faster.

Edit: This doesn't get you a working JDK with the latest versions of jdk 6 and 7. Many of the jar files (eg rt.jar) are compressed so they need to be decompressed using unpack200.

Just go through each directory looking for files with a .pack extension and unpack them using unpack200, eg: .jrebinunpack200 .jrelibrt.pack .jrelibrt.jar

This allows you to run java programs however I still had trouble with Eclipse as there was some issue with annotations, so there's probably another step that is missing.

In the answers to this similar question on Superuser is available a script that automatically finds all .pack files and unpacks them in the right folders.

Starting with Java SE 7u21, Oracle offers a so-called Server JRE for download. This is a standard .tar.gz archive that you can extract anywhere on your computer. Although the download is called JRE, it contains a 'normal' JDK subdirectory (including the javac compiler etc.).

Instructions:

• download the 'Server JRE' from Java download site
• extract the .tar.gz
• add the bin subdirectory to your PATH

Oracle changed the package format in update 102 as pointed by @Webrjn on a previous answer at this question, but the unpack method still works with two more unzip actions:

1. The installation executable of the JDK is a zipped file, so just unzip it with 7z to any folder you want.
2. Go to the directory .rsrc/1033/JAVA_CAB10/.
3. The only file there is 111, which is also a zipped file containing tools.zip. Unzip it to get tools.zip.
4. So now perform the original unpack process, by unzipping tools.zip to your desired java installation path.

5. Open a windows command prompt and run:

   The unpack200 program complains about garbage at the end of the files, but the unpacked jars are tested ok by 7z.

6. Java source src.zip is within the file 110 located inside .rsrc/1033/JAVA_CAB9.

By the way, update 101 only contains the tools.zip file and can be installed with the previous unpack method.

Here are all the steps that got the JDK installed on Windows 7 without admin rights.

1. You need the cabextract program to extract the installer files. I tried 7zip but it didn't extract the cab properly. Instead, I used cygwin. You can get the setup.exe program from their website, but you must rename it because Windows assumes that anything called 'setup' requires admin rights. I renamed it to cygwin.exe. Run that. It'll ask you where to install. I chose the cygwin directory in my home directory. When the pop-up asks you which programs to install, type 'cabinstall' in the search bar. Expand the 'Archive' section and make sure the 'cabinstall' is not set to 'skip'. (Click the 'skip' text until the highest number shows.) Proceed with install. This takes a few minutes.

2. Optional: Add cygwinbin to your path. Do this from control panel, user accounts, change my environment variables, edit PATH.

3. Download the JDK. I downloaded jdk-6u45-windows-x64.exe.

4. In the directory where that file is: mkdir tmp

5. cd tmp

6. cabextract .jdk-6u45-windows-x64.exe

7. Make a new directory for the actual JDK. I used jdk in my home directory.

8. Extract the tools.zip file into that. It comes with the Java runtime, so you don't need the other files in the original cab, such as jre.msi.

9. Unpack all the .pack files. You can do that manually by running the bin/unpack200 program on them, or use bash (if you installed cygwin above):

   1. bash

   2. for f in $(./cygwin/bin/find . -name '*.pack'); do bin/unpack200 $f ${f%.*}.jar; done

10. Add jdk/bin to your PATH (see step 2 above).

1. Download the JDK
2. Extract it by using 7 ZIP (Extract the exe file)

It contains a single file tools.zip, which contains all the files we need.Extract the tools.zip to the desired JDK directory (e.g. “D:JavaJDK”).3. Unpack

Now we need to unpack a few files packed with pack200. We do that by executing this script in a console windows inside the JDK directory (e.g. “D:JavaJDK”):

Regard that you will have to adjust the path of the unpack200 binary (“D:JavaJDKbinunpack200”) to your chosen directory.

4. Congrats you now have a working, portable JDK!

I guess you are on Windows.You cannot install the JDK provided by Oracle without administrator right. What you can do is installing it on an other machine (or find a machine where it is installed) and copy the jdk dir.

jdk-8u102-windows-x64.exe no longer works with the unpack method, Oracle seem to have changed the package format.

Maybe a good alternative is to use OpenJDK, here is an unnoficial build for windows, so you can download the Zip file extract to any folder and set the JAVA_HOME for your windows user. I ran Android Studio this way.

If you can install it on any other machine then this solution will help you.

• Install it on another machine.
• Bring the jdk folder on your machine and set system and classpath variable to the path where you have copied the jdk folder. You should be able to run your programs.

The method presented by Lawrence works but you can also use 7-zip and git bash to do the whole thing without much trouble.

NOTE: git bash comes with some gnu utils and unpack200 is one of them.

Rheb possesses a C-terminal CaaX box motif that is modified by attachment of a farnesyl isoprenoid moiety that mediates localization to cellular endomembranes. Rheb activation of mtor.

There is another small thing to do though. The src.zip file which comes with JDK is not present after the unpacking so to do that you can download the Linux tar.gz version and unpack it twice with 7-zip and then copy the missing src.zip file to the windows unpacked JDK.

Not having the src.zip is not a big deal but it will provide you easy access to some JDK sources in tools like Intellij IDEA.

Here you go man, Good luck. This worked for me.

1Insert your portable USB drive into your home computer's USB slot.

2On your home computer, navigate to the 'Download Java JDK' link in the resources section.

3Click the red 'Download' button. When asked to log-in, click 'Skip this step.' Click 'Save file' to download the file to your computer.

4Double-click the '.exe' file you downloaded to begin the installation wizard for Java SE 6. Click 'Accept' to the License Agreement.

5On the Custom Setup page, click the small hard-drive buttons next to 'Source Code,' 'Public JRE,' and 'Java DB' and for each select 'Don't install this feature now.'

6Click the 'Change..' button on the bottom right corner, then from the drop down menu, under 'Look in:' select your portable usb drive. Click 'Create New Folder' button in the in the top right corner (the folder icon), and name the new folder 'JDK'. Select the JDK folder and click 'OK.'

7Click 'Next' and wait while Java installs.

8Open Notepad by going to 'Start,' 'Programs,' 'Accessories' 'Notepad.'

9In Notepad, copy-paste the following two-line batch script:set Path=%~d0JDKbin;%PATH%cmd

10Click 'File,' 'Save as,' navigate to your USB drive root directory, and type 'RunMeForJava.bat' as the name of your file and click 'Save.'

11Insert your USB drive into the computer where you do not have Administrator privileges and double-click the '.bat' file in your USB root directory. A Command Prompt window will open. Type 'javac' (without the quotes) to see that Java works and is fully installed.

Nice work by @Lawrence by using Cygwin. Let me show you similar steps without using any external tools.

Installing using utilities at the system without admin rights:

This works on Windows 7 or later on a system without admin rights

1. Download the latest version of JDK: You can find it here http://www.oracle.com/technetwork/java/javase/downloads/index.html
2. Use 7zip tool to extract the executable into a directory. Again extract the inside tools.zip file within.
3. Goto .jrebin Use SHIFT and Right Click and open Command Prompt.
4. Type unpack200 SRC DST. Inplace of SRC: Search *.pack files within the extracted directory, copy paste the directory location of .pack files, Inplace of DST: Use the same path of .pack files, and replace the filename with .jar
5. Do this for all the .pack files available in the directory. (Some 6-8 files are there for JDK8u65)
6. Launch Eclipse, choose a project, click Alt+Enter, click on Build Path
7. Goto Libraries, remove available system JRE if any. Click on Add Library, choose JRE System Library then NEXT, Click Alternate JRE , click on Installed JREs. Click Add, Standard VM then NEXT, choose Directory.
8. Now choose the directory location of the extracted JDK you performed in step 2, then click FINISH, APPLY then OK

You must be good to go to run the project without actually installing JDK.Cheers!
