This program comes without setup program, just unpack the ZIP archive to the desired target directory.
The DOS Programs of Isg-Software are written in Borland Pascal 7. One routine of Borland causes a runtime error when starting the program on a modern, fast computer!
For this case you can download a patch here that changes the exe file, so that it can be executed correctly again.
This patch does not come from Isg-Software, no guarantees are given!.
