--- Comment #8 from Anastasius Focht focht@gmx.net --- Hello folks,
for documentation: The 'OnlyUseLatestCLR' registry tweak is added by default in recent 'winetricks' (master, v20201206, v20200910).
* https://github.com/Winetricks/winetricks/commit/1131bf0b2235628fdec050983a96... ("dotnet40: use OnlyUseLatestCLR registry setting instead of dotnet20 to avoid WINEPREFIX update popup")
* https://github.com/Winetricks/winetricks/commit/7368a55d7e434bf840210164f516... ("dotnet45: use OnlyUseLatestCLR registry setting to avoid WINEPREFIX update popup")
You don't see the message boxes anymore upon WINEPREFIX update if .NET Frameworks 4.x were installed by these winetricks versions.
Regards
