Hi Cyndie,

Downloading and installing the full program would be right near the
top of my list of options. Even when the software is put onto CDs,
things can go wrong and the program on CD will not work as it should.
Although there are routines that attempt to ensure that no data is
lost, data can be lost during a download. The loss of one bit is all
it takes to corrupt some instruction. A user might use an application
for years without ever seeing the results of that corruption. On the
other hand, they may see problems when they first try to install that
program.

If we stop and consider just how complex an application is, it is
rather amazing that a computer even works. One of my early printers
was a nine pin, dot matrix printer. If a pin failed to make a dot, the
character could still be interpreted by a human. The loss of one bit
in an 8 bit character can not be interpreted correctly by a computer.
Yet we download and install 20 Megabyte applications without a problem
most of the time. That is 160 million bits that must be transmitted,
received, and installed without loss.

Imagine the a building is to be built using 160 million bricks. There
are two types of bricks, some are ones and some are zeros. The bricks
can not be laid just any way. Every brick must be laid in a precise
pattern of 8 ones or zeros. There are 256 possible 8 brick patterns
and each pattern must be laid in the right place. Depending on where a
brick is located, the presence of a one where a zero should be could
have a major impact. It might mean that the door into the building can
not be installed and thus make the entire building unusable. Or it
might only be discovered if a janitor tries to install a coat hook
behind the door in the third floor utility closet.

Brick buildings are common and sometimes the bricks are laid to form a
pattern. However, if an architect designed a brick building where
every brick in the entire building had to be in a precise location, I
doubt that most contractors would even bid to lay the bricks. They
would know that the task is almost impossible to accomplish. If
payment for laying the bricks depended on every brick being in the
right place, the contractor would submit a bid so high that nobody in
there right mind would accept the bid. If that were not bad enough, we
order the bricks needed for the original design but when we see the
design and don't like it, the architect makes changes. Loads of new
bricks are shipped to replace many of the brick patterns. Again the
owner wants something different so more bricks are shipped and used to
make different patterns. Does building such a building sound
reasonable?

We expect 160 million bit applications to be built without one bit
being wrong. Worse yet, once the application is built, we expect it to
be shipped as ones and zeros and not loose a bit. The Internet
shipment does not go in one batch. The shipment is broken into packets
that get shipped individually. Some packets may go one route and some
by a different route. Those packets are then reassembled and installed
as an application. Then we expect to rip out a third of the bits and
replace them with new bits. The fact that this is done, most of the
time, without problems is truly amazing.

IMO, if problems arise in an application and few, if any, other users
see that problem, the cause might be a bad download or installation.
My first choice is to assume that the download was good if the number
of bytes match what other users have. I would then re-install that
download. If that fails to fix the problem, I would bite the bullet
and download the entire application. I have a slow dial up connection
and 20 MB downloads take a long time. Yet, I have downloaded the full
release when the upgrade did not work as expected. It may take two
hours for my computer to receive that download but I can do other
things during that two hours. I don't loose two hours, I just loose
two hours of computer time, if I am lucky. If I am not lucky and have
been dropped off line, I have to resume the download. I use "Get
Right" and it seems to be working well. I had to resume four times
during one download but once it was completed, the number of bytes
matched and everything worked as expected.
