+- **IMPROVED: Registry Wine Binary Detection**: Uses user's configured Proton for better compatibility
+- **IMPROVED: Error Handling**: Registry fixes now provide clear warnings if they fail instead of breaking entire workflow
+
+---
+
+## v0.1.6.2 - Minor Bug Fixes
+**Release Date:** October 23, 2025
+
+### Bug Fixes
+- **Improved dotnet4.x Compatibility**: Universal registry fixes for better modlist compatibility

+
+### Critical Bug Fixes
+- **Fixed Multi-User Steam Detection**: Properly reads loginusers.vdf and converts SteamID64 to SteamID3 for accurate user identification
+- **Fixed dotnet40 Installation Failures**: Hybrid approach uses protontricks for dotnet40 (reliable), winetricks for other components (fast)
+- **Fixed dotnet8 Installation**: Now properly handled by winetricks instead of unimplemented pass statement
+- **Fixed D: Drive Detection**: SD card detection now only applies to Steam Deck systems, not regular Linux systems
+- **Fixed SD Card Mount Patterns**: Replaced hardcoded mmcblk0p1 references with dynamic path detection
