First of all, please uninstall the program from the system again (using the appropriate Windows function).
Now please manually delete the "installation.ini" file, which is a configuration file that was created during the first installation procedure. You can find this file in the following location on your hard drive:
*Under Windows 10/8/7/Vista:
*Under Windows XP:
C:\Documents and Settings\All Users\Application Data\xara\[program name]\installation.ini
Once you have located the "installation.ini" file, just delete it.
The location might differ depending on your choices during the installation process. E.g. the program might be on a different hard drive partition other than "C". In order to browse all of these system directories, you might also need to reconfigure your Windows Explorer to show invisible folders and files.
Once you're done with this procedure, please reinstall and activate the program.
