Cura 3.0 without response choosing modify G-code

[Dinoding 2]

Someone help me!!!  Trying to use "pause at height" function to print some multicolor pring. Installed Cura 3.0 several times, still no response when I click "post-processing" and then "modify G-code".  I'm using Windows 7 with newest updates.  I tried using other version (2.7 & 2.6) and couldn't make the modify G-code function appear when click it either. My printer is Creality CR-10.  Could it be the reason of printer?  Or, I am missing something.  The installation seems normal when I did it.

There is a "cura.log" file where Cura logs its output. Search for that file and take a look inside. Maybe there is a clue about your problem.
