RSA 2013 to RSA 2014 Pro network license issue
Autodesk customers already owning Autodesk® Robot™ Structural Analysis 2013 will be automatically upgraded to Autodesk® Robot™ Structural Analysis Professional 2014.
For the network installations under subscription, as usual once upgraded, you will need to get a new license file. The new license file will be valid for the current and prior 3 version of the product but, this concerns the Professional versions only.
In fact, if you previously had an Autodesk® Robot™ Structural Analysis 2013 network license, you will not be able to get a license from the new file.
You have to request a combined file that integrates both the 2014 Professional and the 2013 (http://www.autodesk.com/licensesupport).
Note: combining the files that you own won’t work as they have different issue dates.
If you upgraded from Autodesk® Robot™ Structural Analysis 2013 Professional version everything is fine with the new license file.
