Hi,

In Maui template we have:

fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");

fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");

Later I publish the app as exe.

When I create setup with installshield 2016 the app install successfully.

When uninstall it from control panel it removed successfully but the fonts of computer are italic.

When installing again the app the fonts become normal.

What is the purposes of these fonts above-do we need it?
Where the problem come from: Maui or Installshield?
How the problem cab be solved ?

Thanks in advance,

Hello,

I found an old thread from you - Fonts are italic when uninstalling unpackage maui app when using installshield - Microsoft Q&A

What is the purposes of these fonts above-do we need it?

By default, .NET Multi-platform App UI (.NET MAUI) apps use the Open Sans font on each platform.

True type format (TTF) and open type font (OTF) fonts can be added to your app and referenced by filename or alias, with registration being performed in the CreateMauiApp method in the MauiProgram class. This is accomplished by invoking the ConfigureFonts method on the MauiAppBuilder object. Then, on the IFontCollection object, call the AddFont method to add the required font to your app.

Please see Fonts in .NET MAUI - .NET MAUI | Microsoft Learn

Where the problem come from: Maui or Installshield? How the problem cab be solved ?

I tried to uninstall an app on my Windows machine, the issue doesn't appear. InstallShield is a third-party component and is not supported on Q&A. You could report the issue to the official community of this plugin for further help.

Best Regards,
