tandem.design and kirkPJS , kindly uninstall any Enscape version you still have on your machine (any release or preview) and then re-install our Enscape preview for all users. Simply start the .msi installer -> Advanced -> "Install for all users of this machine".
If you've installed our current release, or any version of Enscape with our .exe installer and you've decided to also install it for all users before, then complications can occur when you install the preview for only the current user on your machine.
Let me know in case this doesn't resolve your problem!
looks like the full uninstall worked, thanks!
