I have run the setup wizard on a form that runs utilities to to update an application. One of the routines is the to run the SDT 5.1 update utility the code is as follows:

set classlib to dbcxmgr additive
oMeta = createobject("MetaMgr")
oMeta.SetDatabase("ls")
set step on
if oMeta.oSDTMgr.NeedUpdate()
	if oMeta.oSDTMgr.Update() = .f. then
		=messagebox('Update Needed, but not Executed')
	endif
else
	=messagebox('No Update Needed')
endif 
release classlib dbcxmgr
release oMeta

If I run this form in development mode everything works great. When I build the executable and run on a customer's site I get the error "Unknown member osdtmgr".
