Sorry about that, could you try deleting the dotnet folder it mentions inside your StabilityMatrix-win-x64\Data\Assets\ folder (while SM is closed), then try the installation again? Seems we're not properly detecting & upgrading the older dotnet install.

Done that, and this time SwarmUI has successfully installed. I have no idea why, but seems that there's something in the old dotnet folder that is bugging out somehow.
