[DUG] D2007 / cant save .tlb file - COM issue

Let me get this straight.
You cant use the auto-registration as it accesses the registry
You cant use RegSvr32 as it doesn't register exes.
How exactly is one supposed to register an exe that provides COM
support? Btw The only machine in this equation that is Vista is my
machine. The other machines are all Win XP running in admin mode.
We have found an older copy of our software, that I assume has
auto-registration turned on, as it does create the entries when run.
I really want someone at Code gear to yell at !!! This is my third day
on this one issue, I have work up the ying yang that I cant get done
and I seem to find a new bug in D2007 every time I blink.
Angry Rob
(feels somewhat better now after venting !).
