JFLEX installation error

Question

I am trying to install JFLEX on my windows 8 64-bit desktop, in order to do some university coursework.

I have downloaded the files and then performed the following steps:

Opened the batch file named JFLEX, at the following address:

C:\Users\ALEXOM\Documents\jflex-1.4.3\jflex-1.4.3\bin

I right clicked and chose the option to edit, which opened notepad:

I then changed the following 2 lines:

set JFLEX_HOME=C:\Users\ALEXOM\Documents\jflex-1.4.3\jflex
set JAVA_HOME=C:\Users\ALEXOM\Downloads

The second line is the folder that contains the file:

jdk-7u40-windows-x64

I then saved and closed this file and double clicked the batch file that I have just edited.

It opens a command prompt which says:

The system cannot find the path specified

This window then closes instantly

Any ideas what I am doing wrong?

Answer 1

When I was just working on this yesterday, it required that JAVA_HOME was the jdk directory itself. So, I would suggest trying

set JFLEX_HOME=C:\Users\ALEXOM\Documents\jflex-1.4.3\jflex
set JAVA_HOME=C:\Users\ALEXOM\Downloads\jdk-7u40-windows-x64

Hopefully this works
