I've never updated CTE on Linux, hence my question just to be safe: the downloaded zip file the same for all three supported operating systems, right?
Yes. Just drop the ZIP file on the Dashboard.
However, if your version dates before the integration of a the Java runtime (CafeTran 10 Croissant), it might make more sense to make a new installation and migrate any relevant files to it.
Igor, what would you recommend in that case?
If you current CTE version on Linux contains the runtime folder in its installation directory, you can update as usual. Otherwise, reinstall (download and install again) the program to run it with the embedded latest version of Java.
Thank you Jean and Igor.
