 You might also get an "exception caught" error if you don't have a correct license for TOPAS. With TOPAS academic, make sure you have the licence files saved in the same directory in which TOPAS was originally installed.  If you move directory or computer you have to contact Alan for a new licence.  To check if it is a licence problem try running one of the pre-written example INP files through TA.  Or open a dos command or powershell window and go to your TOPAS directory.  Type "tc.exe test_examples\zro2.inp" (or any other INP file) and see if that runs.  If neither works it's probably a licence issue.

-The instructions on the web at http://www.dur.ac.uk/john.evans/topas_academic/jedit_setup.htm for jedit4.2 have worked for everybody except one person.  I've simplified the process slightly for jedit4.3, though this hasn't been tested by many people ([[http://www.dur.ac.uk/john.evans/topas_academic/jedit43_setup.htm]]).
+The instructions on the web at http://www.dur.ac.uk/john.evans/topas_academic/jedit_setup.htm have worked for 1000s of people.  Problems normally only occur if you miss a step out, or don't have appropriate privileges on your computer.  If you can't get jedit5.n working, you can try the older jedit4.3 or jedit4.2 instructions.
-===== I'm that one person, what do I do? =====
+If your university has blocked use of jre (java run time environment) then openJDK 21 seems to work.
+If all else fails, try watching the jEdit setup video on youtube (linked on the left or above).
-jedit4.2 has worked to my knowledge on several hundred computers with different flavours of windows.  The one failure was on a vista machine.  There upgrading to jedit4.3 did the trick.  If you do want to upgrade to jedit4.3 you'll need newer versions of the plugins.  See [[http://www.dur.ac.uk/john.evans/topas_academic/jedit43_setup.htm]]
+==== jEdit menus are broken ====
-===== When I click on the menus on the left I don't get keywords appearing, just a load of computer code =====
+You'll sometimes find that when you click on jEdit menus you get a load of "computer code" appearing, not the expected TOPAS commands.
+There's a tick box called  "Execute Scripts" in the bottom left of the XInsert menu window.  Make sure it's ticked.
-There's a tick box called something like "run scripts" in the bottom left of the menu window.  Make sure it's ticked.
+==== The menus don't seem to work in jedit4.3 ====
-===== The menus don't seem to work in jedit4.3 =====
 By default they were single click menus in jedit4.2 but are double clicks in jedit4.3
