Regarding the results: Please send your OptiSystem file to firstname.lastname@example.org with a description of which results are differing from 14.1 to 14.2. We will have somebody from our team take a look for you.
The price listed by the other forum member is not accurate (as it depends on several factors). Also, we have several purchasing options (lease/perpetual, standalone/network, etc.) that all affect the overall price. You would need to contact us via email in order to receive a formal quotation.
Note: Please do not post product prices on our forums!
