Tlibimp in new bcb3 patch not working

I loaded new patch into bcb3 - when I try to run new tlibimp for an ocx it
is not creating the files in \lib - I have dutifully followed the
instructions in the readme - running under NT4sp3 under adminstrator
the error says: "cannot create file ...lib\mapobjects_tlb.h"
any ideas?
