Why do I get Deadline Render Manager errors with R21 and my Maxon Account?

If you are getting licensing errors with command line using your *Maxon Account in Deadline, it could be your Commandline Render of Cinema 4D has no licensing set up.

Recommended, secure method
To set up licensing, start the commandline exe / app manually in the console without any render commands attached:
Error running authentication: No License Model defined [license_impl.cpp(129)]
----
Enter the license method:
1) Maxon Account
2) Maxon License Server
3) RLM
Q) Quit
Please select:
Choose the licensing method you want to use, and type in whats asked (license server connections / myMaxon credentials). This must only be set up once. For my.Maxon it might require a re-login if our terms-and-conditions change though.


A convenient but not secure method is the following (it will store your my.Maxon password in clear text, which is not secure and a risk in many scenarios):
  1. Go to the Maxon Cinema 4D R21 > resource folder
  2. Open the config.txt (not the config.c4dpy.txt) with notepad running as administrator (if you try to open it with notepad not as admin it will not over write the current config.txt file and ask you to make a copy)
  3. Scroll to the bottom of the txt file and type this code in:
    g_licenseUsername="YourMyMaxonEmailAddress" (must be in quotes)
    g_licensePassword=YourMyMaxonPassword (password does not have quotes)
    1. If you're using a License Server, instead you will need to use g_licenseServerUrl="http://[username]:[password]@[ip adress]:[port]"
      1. Note that on R21 the username and password flags were not available, so you'd just use IP and port
      2. For this reason using a License Server can be much more secure as the passwords for your MyMaxon account will not be visible, only the password you set up yourself on the License Server.
      3. Finally, note that quotation marks are required
    2. Similarly for RLM you could use g_licenseServerRLM="[servername]:[port]"
      1. note that quotation marks are required
  4. Save the the config.txt
What this will do is bypass the license manager and the need to enter which account your are using in the command prompt and automatically log you in.

*NOTE this is only if you are using your Maxon Account to license your command line licenses. If you are using the Maxon License Server or RLM this will not work.
