Nitecrawler and V4 64 bits ascom

Also checking if it works well together (i.e. migrating from 32 bits to 64 bits).

Yes, it should. I’d recommend just downloading the 64bit beta and giving it a shot. It will install separately from the 32bit version so you can use them both and switch between them.

App launchers also designate their “bitness”
