Can't get programs to run

[J]

Hello,

I'm trying to get the hardware simulator up and running for Chapter 1, but I'm having trouble doing so.  As far as I can tell, I've got everything set correctly: the program is in its own directory and I've got Java up-to-date.  Whenever I try to launch the .bat file, after clicking its ok to run the file, the command prompt window flashes on the screen and disappears.  What am I missing/doing wrong?

Run the simulator from the command prompt rather than double-clicking the .bat file. There's some Java error output you need to see.

Thank you.

Ran it in CMD and got the ''java' is not recognized as an internal or external command, operable program, or batch file.'

I checked my JRE and discovered I didn't have the 64-bit version.

Thanks again!
