Our program, HICSOAP PROFESSIONAL, does work with Citrix, Microsoft Terminal Server, and Microsoft RDS. The license for such use is 3 times the normal cost or 3x$1895=$5685 plus a required $1000/year support fee. This allows you to install it on as many servers as you need to make your server work. And it allows an unlimited number of people to access it via your remote server.
Just like the normal license, locations in different cities need separate licenses.
Some of our customers started using our program in a Citrix or MS Terminal Server environment before we created this special license. In this case, we offer very reasonable upgrade pricing from a normal license to this server based license. Please email email@example.com for details.
