jar files

Fixing .jar file opening on Windows requires two steps:

• Open the Control Panel, and chose "Default Programs - Associate a File type or protocol with a program". Find .jar extension (Executable JAR file) there, and pick Java as default program to open this extension. It will probably be listed as "Java Platform(SE)".
  A faster alternative perhaps is straightforward right-click on a .jar file, and then change associated program by clicking on the "Change..." button.
• Now open the regedit, and open the HKEY_CLASSES_ROOT\jarfile\shell\open\command key. Luckilly for us, we may specify parameters there for the (Default) value. This is normally: C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %*

I Hope this Answers your Question!

 

Cannot open .jar files

Hi Hardy,

Possible cause why you were not able to open .jar files might be compatibility issue. To provide you the appropriate resolution, we would like to know the following information:

• When did the issue start?
• Are you getting any error messages?
• Do you have a third-party antivirus? If yes, we suggest that you disable it for the meantime.
  

Regards.

Any suggestions on how to resolve this? Thanks!
