Windows version


UniPatcher for all windows versions:



Please back-up your old Unity_lic.ulf file, just in case you want to work with (eg: rename it… “Unity_lic.ulf.old“).
There is no need to back-up licenses previous to v2017.

This new version caters for the new licensing system for 2017.2+ and the old licensing. It will correctly handle v4, v5 and both v2017 versions of unity.


Patcher changelog:
Patcher now self-checks if it has been “Run as administrator“. It prompts the user if it has not been.
A license key is now randomly auto-generated at the start, and still allows you to regenerate more [one less click for you].
The patcher just asks for the location of the executable, and no longer asks for which version you want to patch.
It works out the version of the selected *.exe and patches it accordingly.
All v4.x.x and v5.x.x releases are handled.
Tested on v4.6.9p2(x32), v5.2.3p2(x64) and v5.3.0f4(x64).
The PATCH button can only be pressed is a valid executable is found within your chosen folder.
This patcher now creates a U*i*y.exe.bak (backup of the the original exe) prior to patching. Useful for those wishing to build a release game/app with the untouched editor.

  • Thomas Maw

    You sir are a legend! Worked like a charm! My eyes thank you XD

  • Mèo Điên

    How about Unity 2017.1?

    • Blck Hrtzz

      Search for this “00 84 C0 74” and replace with “00 84 C0 75”. 🙂

    • beBoss

      Sorry, i was really busy lately..
      I am going to update the tutorial in an hour or two. And will keep it updated as much as I can.

    • oOPHINOo

      Unity 2017.1 OSX isn’t changing colour with this new patch. Any idea why it would not work?

      • beBoss

        It’s not changing the colour or it’s not the pro version at all? And Are you sure that you have done everything right, mean followed the steps and have patched the right version of the software? Every patch is for specific build 🙂

  • disqus_wd1u1LxpPN

    Can’t seem to get the hex working with 5.6.3p1. Any advice?

    • beBoss

      If you are using windows version, use the patcher. I mac’s one then download the patched files.

  • Geoffrey Hendrikx

    What about 2017.2.0b11?

    • beBoss

      Mac version? There is already posted link about 2017.2.0b11:
      Unity 2017.2.0b11(mac).zip

      • Geoffrey Hendrikx

        windows version

        • beBoss

          “UniPatcher_v2017.6” should work.
          if still have problem, try with “Manual activation” and load last licence version of the mac version.


    In Unity 5.4. I am able to Remove Splash Image Please Suggest


    Sir Another Request Please
    Camtasia 9 Crack for mac OS

    • beBoss

      There isn’t Camtasia 9 for macOS

  • Manzoor AHMAD

    Bro Unity patch for Window for Unit 2017 not download …….

  • Thomas Maw

    Any chance you could release a patch for version 2017.2.0p2 for mac? Thanks man!

    • beBoss

      Sorry for the delay, but I am really busy keeping the thread everyday updated. Soon an autopatcher/patcher for MacOS will be released and would make the process really easier 🙂
