Neither the ‘click here to update’ (from the app) nor the ‘download latest version’ (via website) worked - the former gave me the usual; ‘installation failed’ and the latter simply reinstalled the current version.
I will reboot and try the manual install-over-current method if the reboot isn’t the magic that’s required.
(edit: win7 though, this might be the one where we finally have to upgrade our OS)
Update: with the ‘download latest version’ method, the new version is downloaded (I checked), the installer looks like it’s doing everything right, but for whatever reason does not install this new version. Weirdly if I run the exe from the temp downloaded folder it starts and that bit at least is the new version. Still have access to mapped Z: drive though so not a complete disaster but can’t get to other cloudshares (scratch that, I can get to those too).
Next attempt, uninstall and start clean.
