I an having problems installing the recent update.
I am running Windows 7 64bit and when I launch the updater after a brief moment where it shows a progress bar, it disapears without any further progress being made. Halion 4 remains unchanged.
I found out that if I set the compatibility to Windows XP SP3 (for the executable), the update process works. Maybe a recent Windows 7 hotfix broke the Steinberg installer?
