What happens when something goes wrong? When you open the patched file you can see, in the places of your changes in the code - something like in the below screenshot:
How to fix it? Usually you'll have to start your work since almost beginning (the cleaned file should be fine). That's why it's worth to save each stage of your work (...patchedInd1.dll ...patchedInd1&2.dll and so on)

The last topic, about which I'd like to mention is a preparation of the final edu package.
So, we have 3 below files to be included in the zip package.
...
http://s29.postimg.org/tdyxvif6v/JD_Edu.png
First of all, change the name of patched file, as below:
 
http://s11.postimg.org/wpmb2r0nn/JD_Edu1.png
 
Then compress all of the 3 files by using any of zip compressors. Such package is ready to import from inside of NT. You can name it as you want...

Good luck!

Cont.
Similarly, we have to make the patches inside of the second indicator and strategy. Jump to the right place in the code by using a "Search" feature as described earlier ... "Clicking in sequence on each item of the search list will move us to the particular localisation".
 
Below you can see the part of code inside of the strategy, which contains also the VendorLicense call. Steps of patching are the same as described above concerning the 1st indicator.
 
http://s21.postimg.org/ia7tz6pjb/JD_4e.png
 
When we finished all the patching work, then we must save the changes. Again - right click on top item of tree will open the list of option - select "Reflexil v1.8" and then "Save as", as shown below.
 
http://s12.postimg.org/c8xdb2gj1/JD_5.png
 
Then, you'll have a chance to select disk folder and the name of patched file. Let's better don't change the defaults. The new, patched binary file will have added the suffix: ".Patched". Lastly click the bottom button "Save"
 
http://s13.postimg.org/4u10t29yv/JD_5a.png
 
When you open a patched file you'll see finally all the changes decompiled in C#. Indeed, the VendorLicense call was definitely removed.

Education: Assembly edition. Patching
 
Let's do the patching. In the left panel is selected Initialize procedure and in the top right panel we can see the C# codes. Inside of red frame there is our annoying procedure, that we're going to delete.
In the bottom right panel the Reflexil is already running. The first tab "Instructions" is selected and inside of the window there are MSIL codes. Now we have to find the place, where the VendorLicense begins.
 
http://s22.postimg.org/io2a2a48h/JD_4a.png
 
Unfortunately, there is no available a search feature in Reflexil, so we have to scroll through the MSIL codes manually and search for the first occurrence of VendorLicense call.
Finally, we've found it. In the row 25. Above it, there are also 4 parameters passed by ldstr (load string) instruction and ldarg0 (load argument 0), which exactly begins the block of all MSIL instructions belonging to the VendorLicense call. We have to delete all of them!
 
http://s8.postimg.org/l2wgbmuid/JD_4b.png
 
Select the specified range of MSIL instructions (as below on the screenshot), then right click over the selected range. From the list of options select: "Delete" as shown below.
 
http://s15.postimg.org/6r7cf2597/JD_4c.png
 
...and eventually we got rid of them! The decompiled code, for now, is not refreshed yet. The changes. we've just made, will be visible after saving and reloading of the binary file. For now, we do not worry about it.

Can be useful: https://en.wikipedia.org/wiki/List_of_CIL_instructions

Education:
 
Now we can explore the cleaned project and view the decompiled source codes in C# - in the the right panel of window.
In the left panel, there are localized and indicated (by the red arrows) 2 indicators and 1 strategy, which are our point of interest in the sense of education. Clicking on each of them will expand the tree structure showing the details and at the same time decompiled C# code.
 
http://s29.postimg.org/5bci92mav/JD_3.png
 
What are we looking for exactly? In my introduction I mentioned, I'll try to focus only on the basic protection scheme, which is widely used and recommended by NinjaTrader. What is it?
The simple answer is: The procedure: VendorLicense(param1, param2, param3, param4);

Which should be removed from the code together with all their parameters. All occurrences.
How do we find them? In JD by using a Search feature. Click on the Search button will open the form window. Select "Full Text" tab, enter the search text "license" and finally click adjacent Search button. Almost immediately we'll get the list with all the its occurrences.
 
Clicking in sequence on each item of the search list will move us to the particular localisation.
 
http://s21.postimg.org/6ug2ll0w7/JD_3a.png
 
Here we can see the detailed code and the place, where a call to the VendorLicense procedure exists.
 
http://s2.postimg.org/anxv4oqmh/JD_3b.png
 
Just now we can proceed to use the assembly editor, I mean - Reflexil. It's impossible (or complicated on this level) to directly edit decompiled codes in C#, so we have to make all the changes in MSIL.
 
"Microsoft Intermediate Language, a programming language that has been standardized later as the Common Intermediate Language"
https://en.wikipedia.org/wiki/Common_Intermediate_Language
 
Let's run the Reflexil from the Plugins menu. It'll split the right panel. In the bottom part we can see the Reflexil extension, which allows to make such binary modifications (simply called: patching, binary patching)
 
http://s21.postimg.org/f7655j07b/JD_4.png

Now we have 2 binary files opened in JD. The obfuscated original and the 2nd, which is cleaned.
 
http://s10.postimg.org/l1pv2iva1/JD_2d.png
 
We can close the 1st, obfuscated file, because we don't need it anymore. Again - right click on top item of tree will open the list of option - select "Remove", as shown below.
 
http://s15.postimg.org/o4fr0vsbf/JD_2e.png
...

Deobfuscation:

Select top item from the project tree in the left panel (OFlowSystem200612.X86), right click of mouse, it will open a list of options.
Click on the last one (De4dot) and then on Obfuscator search. You see it below, on the screenshot.
 
http://s1.postimg.org/ipfgnl6n3/JD_2.png
 
JD (JustDecompile) will ask you for a confirmation. Select OK.
 
http://s30.postimg.org/3v2ibkry9/JD_2a.png
 
Then, you'll have a chance to select disk folder and the name of de-obfuscated file. Let's better don't change the defaults. Deobfuscated, binary file will have the suffix: ".Cleaned". Lastly click the bottom button "Save"
 
http://s23.postimg.org/f3ggk5irf/JD_2b.png
 
When the process of cleaning is properly finished - allow to load the cleaned file into JD.
 
http://s12.postimg.org/eobnxr9rh/JD_2c.png

ok. Let's start.
 
I'll use the OFlowSystem200612 addon in my short guide as an example project, containing 2 indicators and 1 strategy. The binary package is obfuscated by CliSecure, which is (was) the standard obfuscation-protection system dedicated for NinjaTrader. It is still widely used for NT7. Keep in mind, there are quite a lot other obfuscators.
 
For our purposes, it is now no matter how works this sample addition. We'll focus only on the educational process.
Here you can download it: https://www.sendspace.com/file/e3nncd
pw is obvious
 
Obfuscation (software): https://en.wikipedia.org/wiki/Obfuscation_%28software%29
 
I assume, you've already installed Telerik JustDecompile with its extensions (at least: De4Dot Deobfuscator, Assembly Editor - Reflexil)
After running this app your screen should looks like this below:
In the upper right corner of screenshot the plugins manager is selected from menu. As you can see, the Reflexil extension is already installed and shown in the dropdown menu of Plugins.
 
http://s30.postimg.org/4drza4jgh/Jd_0.png
 
Plugins Manager window - here you can install, enable, update all the extensions. You must enable all of them!
 
http://s27.postimg.org/xx97crmwz/JD_0a.png
After unpacking of the sample project on your disk you should see 4 files, as below:
Info.xml
OFlowSystem200612.cs
OFlowSystem200612.X86.dll
OFlowSystem200612.X64.dll
 
In 99.99% of all cases: OFlowSystem200612.X86.dll = OFlowSystem200612.X64.dll Please, try to memorize it finally in your mind!)
 
During importing, NinjaTrader creates OFlowSystem200612.dll and put it together with these two in the folder:
c:\Users\YOU\Documents\NinjaTrader 7\bin\Custom\
For a proper functionallity is enough to have only the final dll: OFlowSystem200612.dll (btw. this is fixed now in version 8)
 
Now we can open our sample project (file: OFlowSystem200612.X86.dll) into the JustDecompile by dragging it into the left panel or through the menu command: Open ... -> File(s) ...
http://s11.postimg.org/w2u3nqftf/JD_1.png
It's worth to select the preferred language as a C# (shown on the screenshot).
In the left panel of window we can see a tree structure of project, which contains: namespaces, classes, methods, types, variables, constants, resources. The right panel shows us a decompiled source codes.
 
By clicking on the tree item in the left panel we can expand the structure and see all its details. As we can see in the right panel a project obfuscated by CliSecure contains this information.

Of course, there is a plenty of possibilities, limited only by the programmer imagination. I'd even say, in theory - infinity. The obstacles which you can find, start since the beginning. I mean cleaning (deobfuscation). de4dot is a brilliant tool but is not able to solve all the casess - especially for a new releases of obfuscators-protectors.
Part of programmers (software houses) don't use a standard protection procedures at all. They've developed their own solutions. It doesn't meant, that their products are safe and unbreakable, but sometimes it's a true challenge...
I don't even mention about the programming knowledge. It's obvious.
 
There is always a good practice to check for a standard words or abbreviations: "http", "ftp", trial, "expir"
Keep in mind the strings can be also encrypted besides the obfuscation. Don't bother with a tough cases. There is still a lot of products/extensions applying these elementary protection schemes. First of all you have to build your skills, experience by a real practices.
You're on the right way.

I had the same problem because port 80 was not free...
The safest solution is to run cmd.exe with Administrator privilieges and run the command "net stop http"

Here you go! :D

Thank you mastertrader for the opening this thread. I'd like to put here some basic info and clues for a future educators. I don't treat it as place for posting your requests nor kind of contest. I'll try to do my best, but, in advance, forgive me for any simplification.
 
First of all you'll need to collect all the required tools.
De-obfuscator: (https://en.wikipedia.org/wiki/Obfuscation_%28software%29)
https://github.com/0xd4d/de4dot
Binaries: https://ci.appveyor.com/project/0xd4d/de4dot/build/artifacts

Decompilator - Assembly editor:
 
You'll need to have something that co-working with the Reflexil (http://reflexil.net):
 
Reflexil is an assembly editor and runs as a plug-in for Red Gate's Reflector, ILSpy
and Telerik's JustDecompile (free) http://www.telerik.com/download/justdecompile
 
"Reflexil is able to manipulate IL code and save the modified assemblies to disk. Reflexil also supports C#/VB.NET code injection."
Another brilliant tool like a swiss knife: dnSpy (by de4dot): https://ci.appveyor.com/project/0xd4d/dnspy/build/artifacts Does its job without the Reflexil.
Personally I'm using de4dot (a few different releases), Telerik's JustDecompile+all plugins, dnSpy and also a few different releases of Reflector (to produce the sources). To be honest, I have in my arsenal also other advanced tools, but it's irrelevant.
Almost forgot: Text editor (even notepad)
 
To read:
https://en.wikipedia.org/wiki/Common_Intermediate_Language
https://en.wikipedia.org/wiki/List_of_CIL_instructions
http://www.telerik.com/products/decompiler/faq.aspx
 
On the beginning I'll focus only on educating the binaries.
Note for a novice - try to download and install the following tools: de4dot (just unpack to the selected folder), Telerik JustDecompile Iinstallation), dnSpy (just unpack to the selected folder).
That's all for now.

This thread is dedicated for the sole purpose of acquiring knowledge and practical technics & methods
in the subject of Ninjascript coding.
 
Here we will concentrate our efforts to gain a better understanding of code/obfuscation and the tricks programmers use to limit software usage.
 
Anyone here who can contribute out of his experience and dealings with coding is more than welcome to
share and help the members here to be code literate & help them to be able to modify,experiment and use code in an effective & fruitful manner.
 
May the force be with us.

Educated version of NT7 works perfectly with both live and demo Rithmic data feed... I have 2 Rithmic live datafeed provided by AMP Futures and both works fine... If you are referring Rithmic demo credential you can apply using AMP website, but be aware that for Rithmic demo you can apply only once and demo credentials last 30 days... I don't know how and what kind of control they use, but Rithmic perfecly can control the demo allowance to 1 use per pc for 1 month... Also changing ip / using proxy to subscribe again and to accept all CME non pro disclosures, I never had success in using for a 2nd time a demo provided by Rithmic...
Here's the link to apply for Rithmic demo:

I'm sorry but it seems that Windows XP doesn't support BitsAdmin (a Windows Power Shell command that allow to download files from command line), it's possible it has been added in the next versions of Windows...
In my opinion you have 3 possibilities:
a) update your pc at least to Windows 7;
b) try to install/update Windows PowerShell to v2.0 on your Windows XP pc (here I read something about this possibility https://www.microsoft.com/en-us/download/details.aspx?id=16818)
c) manage manually NinjaTrader Educator by following these steps:
1) you have to manually download and update occasionally the xml config fie from http://www.ninjatrader.com/NTConfig.xml (when NT7 doesn't work correctly it's time to update the file :-))
2) manually run educator from ninjatrader folder (C:\Program Files (x86)\NinjaTrader 7\Nt7LicEmu\Nt7LicEmu5.06.exe)... Create a shortcut of that file to your desktop to speed up routine of ninja education...
 
if I were you I'd try to do option a) since windows xp it's a really old and non safe system anymore and windows 7 it's not so heavy as cpu and ram request for any pc...
