"Problem Authorizing User for a new Custom Study"
From my experience distributing DLLs to several thousand users, the biggest issue is usually version compatibility between their Sierra Chart installation and the version used to compile your DLL (including the header files). You can usually identify this as the cause of the problem from a screenshot of their "Add Custom Studies" window.

Another issue I've seen is users running cracked versions of Sierra Chart. In those cases, the DLL simply won't work, and they're out of luck.


"is manually copying the DLL to the user's Data folder fine"
100%

"how long after adding a user is the change effective?"
Sierra Chart should be closed when installing the DLL to make sure it properly overwrites the old version, if one exists. Once Sierra Chart is restarted, it should work.


Sierra Chart is in a league of its own when it comes to this and plenty of other things too.
