I get the same error with other apps - Illustrator isn't the only one. I
suspect its an incompatability with the Apple Installer.

I don't actually disagree with any of this, but thought it might be a good
opportunity to remind people/clue in newcomers about the long-term ARDI
strategy, at least as I, a registered Executor customer with no other ties to
ARDI, understand it.

Right now, they're doing everything they can to get a commercially viable
version 2.0 out the door.  The revenue from that will fund development for
networking support, serial port support, better sound, more colors, etc.
This may raise yet more money.  But the longer-term goal, for version 3.0 or
so, I guess, is to make Executor a base onto which one will install a real
copy of System 7.x and run all MacOS functionality.

There are three or so obstacles:

1) Dirty/Clean engineering.  ARDI has figured out most of the Mac ROM
functionality through "clean-room" techniques; they haven't broken any
copyright or patent agreements to figure out what the ROMs do.  Finding out
the remaining undocumented features of the ROMs and other low-level features
involves hiring a new, "dirty" team of engineers to reverse-engineer and
otherwise mess around in Mac innards to find out such details. Those details
will be used to draft pure specifications, which will go to the clean team,
allowing them to cleanly implement that functionality.  A couple of
iterations of this, and the above goal could be reachable, at least in
theory.  So the 6.0.7 functionality is a way of *funding* System 7.x
droppability.

2) PowerPC.  Mat Hostetler, the syn68k (ARDI's Motorolla emulator) has
indicated that a PPC emulator won't be too much work, so Executor should
eventually run PPC binaries.  He's even said that developers could include
native x86 code, and that Executor could declare itself and allow Mac apps to
run natively on the x86 (or whatever other processor Executor is ported to)
if they were developed with such a "superfat" binary.  Tantalizing.  This,
too, awaits more moolah.

3) Copeland.  System 7.x won't be a poor OS laggard for too many more years
before Apple, provided it's solvent, releases Copeland, the next major
upgrade.  (I know it *sounds* like I'm starting a religious war, but I'd
rather not, as such wars on this group get intensely weird.  Best that we can
all just emulate each other, IMHO :-)).  Presumably, once (2) is
accomplished, (3) won't be a big problem, but there may be technical details
I don't know about.  There are also Common Hardware Reference Platform specs
I'm fuzzy on.

In other words, the 6.0.7 limitation isn't final.  BUT, and this is the
tricky bit, it's against ARDI's long-term interests to spend much time
hacking 7.x functionality now when it will eventually turn all that over to
Apple.  They need just enough System 7 support to get a customer base; after
that, lower-level issues have greater marginal utility.

Again, none of this is official, though the dirty/clean room stuff is
summarized from one of Cliff Mathews' posts.
