Has my pre-v1 Fritzing self-uninstalled?

I hadn’t used Fritzing for a while, and the other day, I noticed it was gone from my (only) laptop. I still find .fzz files, but no program. Has the beta self-uninstalled when v1.0 came up, or I’m going crazy (or both)? Or is W10 playing smart with me?

I have never had a Fritzing version uninstall itself so I don’t think that is likely. I always keep a copy of the installer around in a separate file system in case of disk failure, and then reload it. A number of people lately have apparently installed directly (and not kept a copy of the installer) but most of them have been able to recover by accessing the link provided in their donation confirmation email from paypal.
