I have decided to post the compiled executable version of the NSIS Hotfix Installer I made for Deployment Server 6.9 All Hotfixes (6.9.177). This single executable file will patch your Deployment Server(s) to the latest Hotfix.
If you have any problems with the precompiled executable, you can find the original .nsi file here and you can find instructions about how to edit an compile it here.
