The Windows Installer XML variable 'WixUICostingPopupOptOut' is declared in more than one location. Please remove one of the declarations

Question

I have created a setup for my web application using wix 3.7 but on building the WIX setup I got the following Error.

error LGHT0195: The Windows Installer XML variable 'WixUICostingPopupOptOut' is declared in more than one location.  Please remove one of the declarations.

I have searched a lot and got this solution. I have added code below to my Product.wxs

Not worked for me. Kindly help to fixing this issue.

Answer 2

I came across this issue while building an msi using 'WiX Toolset v3.11.2.4516' on Windows 10 and resolved it by adding <WixVariable Id="WixUICostingPopupOptOut" Value="0" /> in 'Product.wxs' file.
