The error above means there was an older version of Sametime Connect client already
running on target system where you were trying to install the new client.
It was running while the new installation was in progress thus causing the failure of new client install.

Make sure that the environment is clean and no older or current version of Sametime client are running on the system and have been removed successfully from the machine.

Make make sure all Microsoft applications like Outlook etc, are stopped and no processes seen in Task Manager.
Also delete all contents of %temp% folder and "%APPDATA%\Lotus\Sametime" folder.
