 ***Version 1.4 - Antivirus blocks "setup.exe"/"SANGUI.exe" due to malware/malicious content***
 
-This is explained further in the [Version 1.4 release notes](https://github.com/SteamAchievementNotifier/SteamAchievementNotifier/releases/tag/v1.4), but to briefly summarise: I have used a tool called [PowershellToEXE](https://github.com/VortexUK/PowerShellToEXE) to convert the original .ps1 files to EXE format.

 I can assure you that I have not included any malicious scripts or executables in the available downloads, but if you're still wary, I have included an alternate version of the GUI application called "SANGUI-PS1.zip" which uses Powershell .ps1 scripts in place of the EXEs. If you wish to install this version instead, please see the installation notes on the releases page linked above.
