Add link to Abort page

As a follow-up to this answer, I'm trying to add the link after issuing Abort command, but for some reason it does not appear, no trace of it when viewed in Spy++.enter image description here

The idea is to add the link above the progress bar, but somehow the macro does not work. Is there a reason for this that I'm missing and is it possible to add that link after calling Abort? I've read somewhere that Abort command can have different effect so I'm guessing this is one of it.

I've tried to make this sample script as concise as best I can and would greatly appreciate any help as I'm still learning NSIS.

Solution

  • Abort stops executing the section(s) code, you must do whatever you need to do before calling Abort.

    Adding controls in a section can be problematic because it executes on a different thread and windows are tied to the thread that created them. If you need the window to stick around longer than the install thread you can create it as a hidden window in the instfiles page show callback and simply call ShowWindow in the section when you need to display it...
