What a neat app. I am using it to write this review. I installed puttytel.exe  which I found by a Google search  on my desktop. First I click on the app remote keyboard  choose remote keyboard as the keyboard  then I click on the puttytel.exe on the desktop with the settings described in the app  and it does work. You can save the settings as default settings so you don't have to enter them each time. So a few clicks and I have the remote keyboard working. Thanks for this app.
