Running JAR Files with Double-Clicks in Windows 7 64-bit

Unable to launch JAR files with a double-click in Windows 7 (64-bit)? Here's how to resolve the issue:

Problem:

Double-clicking JAR files evokes no response. Attempts to modify the registry key (ftype) have been unsuccessful.

Solution:

If you previously assigned the ".jar" extension to a specific Java executable ("javaw.exe") via the right-click option, it's necessary to remove this registry setting.

1. Navigate to the following registry key:

   [-HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerFileExts.jar]

2. Delete this registry key.

3. Run the following commands in an elevated Command Prompt (run as Administrator):

   C:\> assoc .jar=jarfile
   C:\> ftype jarfile="C:\path\to\your\javaw.exe" -jar "%1" %*

4. Replace "C:pathtoyourjavaw.exe" with the actual location of the "javaw.exe" executable.

After performing these steps, double-clicking JAR files should execute them using the "javaw.exe" executable.
