Kindly note
that you can continue to buy and
upgrade WYHLIDAL as
you have in the past without buying a subscription.
Subscription is a new additional purchase option for WYHLIDAL.
WYHLIDAL software
is licensed using different models.
A Perpetual software license offers you the right
to use the software subject to the
terms of the End User License Agreement,
in perpetuity.
A Subscription software license typically allows you to
use the software during the term that
the subscription is valid (or paid). The subscription offer include all updates and upgrades
that take place during the subscription term.
Perpetual May not be Forever
Note that although perpetual licenses may be used forever,
that mitigating factors often dictate a shorter realistic lifespan. If you upgrade
your operating system, hardware or companion software, you may need to
purchase an upgrade for compatibility.
Another issue
is support at End of Life (EOL). WYHLIDAL (and
other software companies) do not support software forever.
Please note
that WYHLIDAL 2009 goes EOL in July,
2014.
