Hello,
I have 2.91 (W10 x64) installed side by side with 2.90.1. I can’t associate .blend file with 2.91 even by choosing “Open With” and searching for the .exe of Blender 2.91 or in the W10 parameters “Choose default applications by file type”. I had to uninstall 2.90.1 to make it happen.
Is there a way to do it without uninstalling previous version please ?
