Here is a solution to install 3.5 to get Affinity Photo running:
To install .net 3.5:
install and switch to Lutris-7.1 Runner
go to dependencies and install dotnet3.5sp1
if the installation still fails, switch to WIndows XP, install 3.5 and switch back to 10
switch runner to Cafe-7.15
Complete installation:
make a new bottle (application environment), Win10, 64-Bit
install and switch to Lutris-7.1 Runner
go to dependencies and install dotnet3.5sp1, dotnet40, dotnet48, allfonts
switch runner to Cafe-7.15
After installation, enable DXVK, Vulkan and add --no-hw-ui in the starting arguments field, as described in previous posts.
