That isn't a WixUI dialog, it's one your team wrote.

@barnson to be clear, when you say "your team", you mean the Windows installer team? The PowerShell wix doesn't define that dialog or text https://github.com/PowerShell/PowerShell/blob/master/assets/wix/Product.wxs

A quick glance shows this line:

<UIRef Id="CustomWixUI_InstallDir" />

CustomWixUI_InstallDir is not something provided by WiX, that's a custom UI code that's somewhere in your source.

Thanks! I'll have someone on my team look into this.

@SteveL-MSFT I'm evaluating issues that are external but required core WiX maintainers' time to resolve.

Can you help me understand a) why this issue was opened against the WiX Toolset initially and b) why a follow-up was required to point out the exact location of the customization in the PowerShell codebase? Thanks.
