You do not need to uninstall the versions prior to the one you wish to install.
In any case, if you wish to delete the files corresponding to the previous version, you can delete the subdirectory "Version XXXX" located in the "CYPE Ingenieros" directory of the unit where the program is installed. The characters "XXXX" refer to the identification of the version, for example "2026".
Before uninstalling or deleting files, you are advised to confirm that you have backup copies of all the jobs that you want to keep and that have been created with CYPE programs of any version.
