How To Run A Jar File Windows 10

If you find yourself unable to open .jar files on Windows 10, it is likely due to ane of the following problems:

*The Java Run-Time Surround is not properly set to run .jar files
*Windows Registry is not calling JRE (Java Runtime Environment) properly

Luckily at that place are a couple of easy solutions for fixing this. What happens for virtually people is that when trying to open a .jar file, Windows volition typically ask what program you desire to utilise to run the program. Of course, nigh people would simply choose the Java.exe, but this has the problem of stripping –jar from the program's execution path. Basically you cannot set the required complex control to open up .jar files by using "Open With…" in Windows 10.

And so what will normally happen is that you'll acquaintance the .jar file to open up with java.exe, yous double-click on the executable .jar, and a command prompt window volition open up for a split second and close, and the program does not launch.

What we need to do is re-associate the .jar file with the Java binary.

Make sure you are updated with the latest Coffee Runtime Environs.
Navigate to your Coffee installation folder, go within the /bin/ folder, right-click on Java.exe and set it to "Run every bit Administrator".
Press Windows + X keys and select "Command Prompt (Admin)" or Powershell (Admin) and blazoncmd
Type the following commands into the prompt (replace the C:\Program Files\etc with your actual Coffee installation folder, for example, C:\Program Files (x86)\Coffee\jre1.8.0_131\bin\java.exe):

ftype jarfileterm=cmd /south /k ""C:\Program Files\Java\jre7\bin\java.exe" -jar "%1″ %*"
assoc .jar=jarfileterm

Or if you want the command prompt to stay open up after launching the .jar file (for debugging purposes)

ftype jarfileterm=cmd /due south /one thousand ""C:\Programme Files\Coffee\jre7\bin\java.exe" -jar "%one″ %*"
assoc .jar=jarfileterm

Now try to launch the .jar file. Depending on which of the steps to a higher place y'all took, the coffee executable should either launch or launch with a persistent command prompt backside it (which will make full up with Java calls from the app, useful for debugging purposes).

However, if the steps did not work, nosotros will demand to tweak your registry.

Correct-click on your Offset button and exercise a search for "regedit", so open it.
Now expand the HKEY_CLASSES_ROOT folder, and scroll down until y'all find the folders "jar_auto_file" and "jarfileterm".

Expand to the following path

jar_auto_file > Shell > Open up > Command

You lot will see a key named "Default". Right-click on "Default" and cull "Modify".
At present in the "Value data" box, paste the ftype control you lot entered earlier in the command prompt, and so information technology looks like the screenshot below, and press OK.
Now exercise the aforementioned thing for the jarfileterm binder (expand jarfileterm > Shell > Open > Comand).
Now get out regedit and launch your .jar file, it should open up properly at present!
