Any ideas? I think I have updated versions of JDK and JRE... I don't know.

 

Try re-installing java, And tell if it works.

 

I've tried downloading JRE and JDK again... didn't work.

 

Right click the program, click edit,

and find all lines that say this

C:\Program Files\Java\jdk1.6.0_XX\bin\javac.exe


Where the XX is, edit that to locate your JAVA folder. Most likely, the xx by default will be 16. That's the old version of java, so go to your \java\ folder and see which one you've got.
