It is very important that you install the correct client software. The client software has to be paired with what the host machine is running. Failure to do this will cause adverse effects on your system.
Here is how you figure that out:
Open up the client software on the HOST machine. It will list the software version on the splash screen. If you miss it click Help and then About once the software launches.
If your system is running something else submit a request and we can supply you with the correct one.
