AIEXTERNALUI empty during patch

Tue May 25, 2021 10:23 am


I use the surface Theme.
The option Use Enhanced User interface is set to "Always".

In several dialog (prepare, progress, or exit),
we have the control condition applied to the control ProductNameTitle
Action : Hide

The property [AIEXTERNALUI] is empty during a path.
So during a patch, the control is not visible.

Hello Philippe,

Please note that this behavior is normal.

A patch is very similar to an MSI file. Our "Enhanced User Interface" option is not compatible with the MSI, this being the reason why the output package is changed from MSI to EXE when using any theme other than the "Classic" one.

Since the Enhanced User Interface is not supported in the MSI, it will not be supported in the MSP (patch) either, therefore the property is not set.
