Installer will crash when run in verbose mode if a lot of components are installed.
1. Select install folder %USERPROFILE%
2. Select installable components: one Qt binary, sources, add-on, logs
3. Crash will occur at around 90%
Could be because of https://bugreports.qt.io/browse/QTBUG-65865
Removing the usage of QPlainTextEdit will fix the issue.
