If you want to make a change to your
current license, please post your request below. Typical changes
are upgrades from YASARA Model to Dynamics, from academic to
commercial usage, or from a single to a group leader license. You
can also add the NMR and YARIA modules here. If you want to change
from YASARA View to Model or Dynamics,
please use the order forms instead.
If you are not sure about the cost of
the upgrade, use the License Fee
Calculator. Your YASARA account will be charged with the
difference between this price and the current value of your
existing YASARA license. Feel free to request more details using
the form below.
