+* AdvancedInstaller v19.4 or better, and enterprise licence. 
+* Qortal has an open source license, however it currently (as of December 2024) only supports up to version 19. (We may need to reach out to Advanced Installer again to obtain a new license at some point, if needed. 
+* Reach out to @crowetic for links to the installer install files, and license.

 ## General build instructions
@@ -10,6 +12,12 @@
 If this is your first time opening the `qortal.aip` file then you might need to adjust
 configured paths, or create a dummy `D:` drive with the expected layout.
 
+Opening the aip file from within a clone of the qortal repo also works, if you have a separate windows machine setup to do the build. 
+
+You May need to change the location of the 'jre64' files inside Advanced Installer, if it is set to a path that your build machine doesn't have. 
+
+The Java Memory Arguments can be set manually, but as of December 2024 they have been reset back to system defaults. This should include G1GC Garbage Collector.
+
 Typical build procedure:
 
 * Place the `qortal.jar` file in `Install-Files\`
