Thanks for updates. I hope support will be able to assist here.
As to the download links and how to update - the Community Edition .exe installer is the one that allows you (or restricts you!) to auto-update.
The Enterprise .MSI installer is purposefully stuck at the specific version of that installer file, just so you can decide when to update.
Also, with our new UiPath Cloud Platform - Public Preview, you can download both installers directly from the Resources tab
