This an older version of Q++Studio compared to your PC settings
Even though most of Q++Studio runs on the server, it is important to make sure that its client modules (the ones on your PC) are the same version as the version of Q++Studio running on the server. This message occurs if Q++Studio notices that the modules on your PC come from an later version of Q++Studio than the one running on the server.
This is usually caused by your Administrator re-installing a previous version of Q++Studio if the latest update has been problematic.
To remedy this, simply click on YES. The Q++Studio updater will be launched automatically and will relaunch Q++Studio afterwards. To be able to launch the updater automatically, make sure that updates downloaded from the Alter Ego web site are always placed in the server directory.
