@albe-rosado I didn’t have to install
windows-build-tools, but I was able to verify thatcreate-proton-appwas able to work successfully. Thanks so much!you are right!, let me update that
I updated the readme on create-proton-app stating the required dep for windows.
@jakubtuchol did installing windows-build-tools worked for you?
