# Agent Requirements

SessionLimit supports installing client (Agent) software on Windows client and server computers.

## General Requirements

Changing the startup type or Log on as settings for any SessionLimit agent software is not supported. Also, no user, including users with administrative rights, can stop or terminate the SessionLimit client service. SessionLimit agent requires .Net Framework 4.7.2. See [.Net Framework 4.7.2](/planning/agent-requirements/.net-framework-4.7.2.md).

## Limitations

* If the start type of the service is changed, the security of the system, logging of the states and any activities will not work.
* The agent supports 64-bit systems only. 

## Windows Computers

To control sessions, SessionLimit needs a client agent software on Windows Computers.
