-## 5. Extract WinMetadata

+
+Bottles pre-installs **Wine Mono Windows Support**, which conflicts with .NET Framework 4.8 and can cause CLR crashes (for example `Unhandled exception: 0xe0434352`) when running the Affinity installer. [Wine Mono must be removed before installing .NET Framework 4.8](https://github.com/wine-mono/wine-mono#composition).
+
+1. Open your bottle → **Tools** → **Legacy Wine Tools** → **Control Panel** → **Add/Remove Programs**.
+2. If **Wine Mono Windows Support** is listed, select it and click **Remove**.
+3. Open **Dependencies** and install **dotnet48**. The install should take several minutes; if it finishes very quickly, Wine Mono may still be present—repeat steps 1–2 and reinstall **dotnet48**.
+
+This workaround is [documented in Bottles issue #2887](https://github.com/bottlesdevs/Bottles/issues/2887#issuecomment-2646118028).
