LoadAddOn(name)
else
local failed_msg = format("%s - %s", reason, _G["ADDON_"..reason])
error(ADDON_LOAD_FAILED:format(name, failed_msg))
end
end
end
TryLoadAddOn("SomeAddOn")
-- Couldn't load SomeAddOn: MISSING - Missing

Patch changes[]
Patch 1.8.0 (2005-10-10): Prior to the 1.8 patch, this could be used to load addons which were not on-demand if they were disabled at start up and then enabled during the play session. The 1.8 patch restricted this to ONLY addons which are truly marked on demand in their .toc files with ## LoadOnDemand: 1
