I know of only two reasons why this error message would show up:
- the Windows system has been damaged in some unusual way and is reporting an incorrect version number that is “too old”.
- The eLicenser Control installer was forced to run in a “compatibility” mode.
Please download the latest eLC installed from http://www.elicenser.net, then open the installer’s “Properties” dialog and check the “Compatibility” page.
There is a checkbox “Run this program in compatibility mode for” that must not be activated.
If you’re inclined to further investigate, you could locate the eLicenser Control installer’s log files located at
There are two entries “windows_os_name:” and “windows_os_version_number:” that will tell you which version was actually detected by the eLicenser Control installer.
