Particular JRE version
Hello all,
I have just recenlty found this example of checking if JRE is installed and then if it is out of date with the included version to update it or just install the JRE.
Now, im not very good with NSIS (yet) still learning. I was just wondering how difficult it would be to modify this script so that it will check for a particular version of java. (j2re-1_4_2_01-windows-i586.exe is the exact JRE installer we use)
Could someone lead me in the right direction with this...
Here is the script:
; Taken from http://nsis.sourceforge.net/Simple_i...with_JRE_check by weebib
; Use it as you desire.
; Credit given to so many people of the NSIS forum.
