Help opening abchr.jar Options

[tawd]

I have the ABC-HR_bin.zip file on my desktop and I extracted all the contents into a single separate folder.

I have installed JRE 5.0 Update 15 x64 on my Windows 7 x64 system.

When I double click on the abchr.jar file it opens in Winrar.
When I 'open with' then browse to Java.exe i get "Could not find the main class. Program will exit".
When I run from command line "C:\Program Files\Java\jre1.5.0_15\bin\java.exe -jar abchr.jar" i get this message:

Exception in thread "main"

I accept that there is probably an error on my side of the keyboard but I would like to find out what it is so I may join this test.

Sounds like perhaps the jar file was compiled with Java 6, and you're running it with Java 5. Try installing the latest Java 6 runtime and see if that works.

Thanks. That did it.
