Cannot open .jar files on your system?
When windows gives you an error message saying that it cannot open
.jar files, this means either:
- You need to identify a program that can open the file or
- Your registry may be damaged.
RECOMMENDED:
In both cases it is strongly recommended that you
run a free scan for registry errors.
