Based on bxtrx's bug fix, the installer should work on all machines that were still crashing. The issue was that Scintilla lexer was not added by default and the users that do have installed other applications, for example TurtoiseSVN, will not encounter any problem, as Scintilla was installed with that.
So based on this, if you still have crash on starting Naro, you may use the installer from here: https://sourceforge.net/projects/narocad/
Also, this build is a snapshot of current nightly build, so a lot of small crashes that you've encountered in your past, are fixed. Based on this, this version appears to be the recommended install version for now and a good way to report other errors based on this.
