ActivClient Mini


ActivClient Mini is a software program developed by ActivIdentity. During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. Upon being installed, the software adds a Windows Service which is designed to run continuously in the background. Manually stopping the service has been seen to cause the program to stop functing properly. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. The setup package generally installs about 13 files and is usually about 2.13 MB (2,232,728 bytes). Relative to the overall usage of those who have this installed, most are running it on Windows XP. While about 76% of users of ActivClient Mini come from the United States, it is also popular in Spain and Italy.
