Something I’ve noticed about the Windows installs, just FYI. I don’t know if this is something that can be “fixed” in the installer, but if not it’s not a show-stopper.
I install each new version of ART into the same folder: C:\Program Files\ART. I don’t keep separate versions, I’ve never had a need to do that. @agriggio is such a good programmer there are never bugs in the new versions! LOL 
But anyway, I just upgrade each new version in place, specifying the same directory each time.
Each new version works fine but I noticed a side effect of upgrading in place: The previous entry isn’t removed from the installed programs list:
(This screenshot is of appwiz.cpl but I assume it’s reflected in the newer Settings app as well. I forgot to check before I fixed it.)
Since they both point to the same installation, removing the older one will (at least partially) uninstall the later version. That’s why 1.17.2 shows an install date of yesterday here – I uninstalled its predecessor and although it didn’t remove all 1.17.2 files, it wouldn’t launch afterward. Re-running the 1.17.2 installer fixed that.
So, the way to straighten it up is to remove the old installer key from the registry, not to run the previous uninstaller.
Go to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and delete the old key. NOTE: I always install for all users, so if you do a per-user install, this might (?) live under Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall instead.
I don’t know Inno Setup so I can’t say whether this is an easy fix or not. Once again, if not it’s no biggie since I now know what to do. Just wanted to pass it along.
