Click once application won't run on windows 7, 8 after allowing dpiAware

[markismail7]

So we're trying to make sure that our application scale perfectly on 4K monitors. We successfully did that, but now the app will not run on windows 7,8,8.1. It can only run on windows 10,11.

So by uncommenting the code below, the app will not run on older windows. Is there anyway around it, where we can keep the dpiAware true for windows 10,11 and false for older versions so users with older version of windows can still run the app?

Note: i'm using .NET 4.7.2 Thanks

Microsoft says: On older versions of Windows, the newer tag will be ignored. So basically if I want my app to run on older versions of windows like 7,8, i need to

remove

<dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">true</dpiAware>

and keep

<dpiAwareness xmlns="http://schemas.microsoft.com/SMI/2016/WindowsSettings">PerMonitorV2</dpiAwareness>

So it would like:

<application xmlns="urn:schemas-microsoft-com:asm.v3">
<windowsSettings>   
  <dpiAwareness xmlns="http://schemas.microsoft.com/SMI/2016/WindowsSettings">PerMonitorV2</dpiAwareness>
</windowsSettings>
</application>

By doing that, my app can run on 4k monitors using Windows 10, 11 and run normally on older versions of windows. Unfortunally, i can't verify that till tommorrow. So i won't be able to sleep tonight lol
