Please read the new UPDATE_INSTRUCTIONS.txt in the ZIP file. This file was added for those having issue updating QAP in portable mode and reporting loosing their config.
Take care to do step #2 in this file. It says that you must quit QAP before updating your QAP folder.
The latest JLicons.dll (v1.5) is dated 2018-12-20. I kept the reminder for those who skipped some versions.
