Do You Need To Install Jump Desktop On Remote Windows Machine?

I purchased Jump Desktop 2.5 for my Macbook Pro and configured it to connect to three different Windows 7 Professional desktop machines.  I have not downloaded and installed Jump Desktop on the three Windows machines.  The Macbook Pro connects perfectly to each of the remote Windows machines and I can share files between the Windows machines and the Macbook Pro.  Do I need to download and install Jump Desktop on the three Windows machines.  I am not interested in installing Jump Desktop on my iPhone or iPad.

Thanks,  Bill
