There is no version upgrade supported for CLE. You need to uninstall the existing version before installing a newer version of it. If you try to install a new version on top of an existing version, you are presented with an option of repairing or removing the existing version. The
option is same as the Microsoft Windows option. If you select it, it troubleshoots the installation issues, such as missing file or configuration issues. You can use the option to return to the normal state. The option uninstalls the existing version of CLE.If you make changes to the MSI installation file, remove the existing version of CLE before running the MSI install program again.
