Use EXE External UI
The Enhanced User Interface improves and extends the controls that you can use when designing the installation interface. You can activate the Enhanced User Interface controls for both EXE and MSI packages. The "EXE External UI" option is more powerful than the MSI Embedded UI equivalent. It also enables you to customize Pre-install UI dialogs shown by the EXE Bootstrapper. You can read more about the requirements and benefits of this option in Enhanced User Interface page.
Always (install, uninstall and maintenance)
EXE External UI will be used when installing the application as well as when performing "Modify" or "Uninstall" from Control Panel.
This option requires the “Override Windows Installer programs list entry” option to be enabled in Product Details Tab.
Only on install
EXE External UI will be used only when installing the application. During "Modify" or "Uninstall" from Control Panel the Windows Installer rendering will be used.
If MSI Embedded UI option is enabled at the same time with the Only on install option, both the install and maintenance stages will use Enhanced UI controls. On install the EXE External UI will render the dialogs, while during maintenace the MSI Embedded UI option will be used for rendering the controls. This eliminates the requirement of overriding the Windows Installer programs list entry.
Windows Installer rendering will be used, if the option MSI Embedded UI option is also disabled.
MSI Embedded UI
The Enhanced User Interface controls will be used, without requiring an EXE as output. You can read more about the requirements and limitations of this option in Enhanced User Interface page.
Use WinUI rendering
Installation UI will be rendered using the modern WinUI controls instead of the classic Win32 controls. You can read more about the requirements and benefits of this option in Enhanced User Interface page.
Use custom frame only if Aero Glass is not available
If this checkbox is enabled the custom frame selected in the Themes Page will be used only if Aero Glass is not available on Windows Vista or later, otherwise the Glass frame will be used.
This option is available only if a custom frame is selected for the currently used theme.
In this section you have the option to specify how the images will be displayed: with fixed or variable size.
Adaptive stretching, based on detected system DPI
The images will be rendered as you would have the option "Use image control intrinsic setting" enabled if the DPI from the machine where the package is installing is at normal scale, i.e. 100%. If the DPI is larger the images will be rendered as if the option "Always stretch images to fit their control window bounds" is enabled.
Use image control intrinsic setting
The images will be stretched or kept at original size, based on the value of the parameter "Fixed Image Size", that you can set for each image independently from Dialog Editor page.
At least an Enterprise project is required.
Always use original image sizes, regardless of control window bounds
The images will be rendered always at their original size, no matter if the image is smaller or larger then the control hosting it, ignoring the value of the attribute "Fixed Image Size".
Always stretch images to fit their control window bounds
The image will be always stretched to fit the control, ignoring the value of the attribute "Fixed Image Size".
This option will not affect the installation dialog's appearance if the fonts on the user's computer have normal size.
