No. Once you are running our newer versions your serial number identifies
who you are to the GLSS web licensing system. This is one reason why
you should never share your whole serial number.
Minor software updates are posted on this web site for you to download
to keep your software series current. These downloads are free and only
require that your license cover that version series.
Major Product releases will usually require a license upgrade in
order to use the new product version series. Users who subscribe
to extended product support will usually get these major releases
as part of their ongoing support subscription. However, it is always
best to inquire about your license before upgrading to a major new
version.
