The comm spot from Es'hail-2 has nothing to do with DATV from the QO-100 transponder, its not the same. Look also at this link:

Thats all I can help, please do not put your tea service to the wall. 
Hello Harry,
check if your sat-receivers can receive a range of 741-749MHz, most can not.
If they can, all you need is a dish, a TV and a standard lnb.
If they can't , you still need all of the above AND either a converter to convert this range into the range your sat-receivers can receive, OR a 18V injector (bias-tee), computer, software and a RTL-dongle. There is plenty of information on the amsat web pages.

If this is the program I need, then I do need help with installing. through images and with arrows and text. Could that be possible or is it possible ?! Mvg
Why do I ask this, because I have 0.0 knowledge of programs

No

Maybe this is not the right playground for you. You should buy or make a converter to convert the downlink into a frequency range your satellite receivers are happy with. This gets you going without any computers, software etc.

Well, to learn, first read the whole thread i sent you. ( I'm afraid, the converter is no longer available from Amsat. I think you can't make your own, so the way to go is : ) Download the software and begin. There are plenty of information in that thread. If you get stuck, ask.
Or do you need very basic help like: Start your PC, click on the ZIP-file, deflate it, clik on the .exe to install? If so, please do simpler things first and then come back to try complex things like getting a rtl-dongle to receive an exotic frequency, sample rate and deal with things like I/Q plot etc..

Why do you want to open a dll?
As long as you only say that something doesn't work without telling us, what you did and what error popped up, nobody can help you.
I strongly recommend you find a forum where you can learn how to install software on windows.
