It is most likely that this error is caused by missing file access rights. Change the file permissions on the .lic file in the installation folder so that
every user has
read and write permissions. The simplest way to do this is to add the user
Everyone.
If this does not help
- Uninstall CTI Data Connector
- Delete the installation folder. Typically c:\program files(x86)\CTI Data Connector
