Now KiCad nightly will install into
No more excuses for not installing 5.99 and testing it!
EDIT: There’s some problem in the latest nightly build installer ATM, see the linked thread. I suggest avoiding it until it’s fixed.

EDITEDITEDIT: I added instructions for easy safe installation procedure unless you want to wait for the official instructions. Just start from scratch. Because we are talking about nightly builds for testing, it may not be worth trying to keep old settings. (4th edit: read the post linked to below if you use 3D models.)
