Some notes on installing Sketchup make on ubuntu 20.04 (should work, not tested from scratch):
Install Dot net 4.5.2 (not sure it's useful)
Based on https://appdb.winehq.org/objectManager.php?sClass=version&iId=31023 run the following :
env WINEPREFIX=$HOME/winedotnet wineboot --init env WINEPREFIX=$HOME/winedotnet winetricks dotnet452 corefonts
We are installing the sketchup make 2017 version, enough for me. Based on https://appdb.winehq.org/objectManager.php?sClass=version&iId=34500
export WINEARCH=win64 winetricks vcrun2013 vcrun2015 corefonts winetricks win7 # Not sur the above works, seems better when launching winetricks, default config then in settings selecting win7. # Download from https://www.sketchup.com/fr/sketchup/2017/en/sketchupmake-2017-2-2555-90782-en-x64-exe wine sketchupmake-2017-2-2555-90782-en-x64-exe
All the steps take a lot of time and many errors are displayed, but it seems to work.
