Issue is the same as this question. As suggested I used tcl8.6, the application worked, but having problems with user interface like glitching UI and not working arrow keys (someone suggested here to use tcl8.5 to solve some of these issues). But when I try to run it on 8.5, it is unable to find itcl3.4, even it is installed, and it is working with 8.6. Question is how could I use itcl with tcl8.5 for this application?
I am asking this new question rather than commenting in the given question due to insufficient reputation.
