java - How to run .jar file by double click on Windows 7 64-bit?

Question

Running a .jar file in a command line works fine, but i am not able to run any .jar file by double clicking on my Windows 7 (64). It seems nothing happens after the double click.

I tried the ftype hint, no success:

ftype jarfile="C:Program FilesJavajre7injavaw.exe" -jar "%1" %*

I reinstalled the JDK 7 64-bit, no success.

Any idea?

If you have previously used the right click and opened with pathoyourjavaw.exe then you will need to remove the following registry key.

[-HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerFileExts.jar]

Then run

C:>assoc .jar=jarfile
C:>ftype jarfile="C:pathoyourjavaw.exe" -jar "%1" %*
