This issue seems to be triggered by "Override Windows Installer programs list entry" option. A fix will be available in a future version of Advanced Installer. We will update this topic when the fix will be available.
Until then, please try to uncheck "Override Windows Installer programs list entry" option and see if it works.
The "Enhanced User Interface" feature set on "Always" will work only if the "Override Windows Installer programs list entry" option is enabled too. So, disabling the "Override Windows Installer programs list entry" option will prevent you from using the "Enhanced User Interface" feature set on "Always" too. So, you should not use the EUI set on always nor the "Surface" theme which needs the EUI set on always.
