In the Houdini documentation for manual installation
https://docs.thinkboxsoftware.com/products/deadline/10.1/1_User%20Manual/manual/app-houdini.html#manual-installation
it has this line for replacing the text in MainMenuCommon.xml
Second, update the MainMenuCommon.xml that was copied by replacing SUBMITTER_DIR with
%localappdata%\Thinkbox\Deadline[VERSION]\submitters\HoudiniSubmitteron Windows,~/Library/Application Support/Thinkbox/Deadline[VERSION]/submitters/HoudiniSubmitteron OSX and~/Thinkbox/Deadline[VERSION]/submitters/HoudiniSubmitteron Linux
If you use %localappdata% in Windows it doesn’t work as Houdini is reading this part, changing it to $localappdata does work
