You may use TestExecute in server-based (or Citrix) environments: you may install TestExecute on a server, open several user sessions on this server, for instance, with the Remote Desktop service, and use TestExecute in these user sessions. That is, you can use TestExecute installed on a powerful server from “weak” workstations (“thin clients”).
The number of TestExecute instances that can be run in sessions depends on your license key. You will not be able to use more instances than the number specified by the key.
To get more TestExecute instances, you can upgrade your license. See Upgrading Existing TestExecute Licenses.
