title: NSIS: How to add custom button to left bottom corner and handle it's click?
body: <p>I tried the ButtonEvent plugin, but when I run compiled example, it fails with memory access error. Maybe it is able to do with System plugin via Windows API or something else? Can anyone show how it can be done?</p>
  
  <p><strong>UPD: Error was appeared because I tried to use non-unicode ButtonEvent on Unicode NSIS. Now example compiles and executes OK, but when I click on TryMe button, callback function is not called and nothing happens. How to determine what is the problem? Can anyone compile ButtonEventMUI.nsi and click on TryMe button? I downloaded latest ButtonEvent version. Using NSIS 2.46 Unicode</strong></p>
