2) Can I use the same license file?
OK, seems like you have the same questions as i do, can you point me to the Docs on the support site, or atleast the same Release notes which you were reffering to?Thanks
On the support site, go to "Download Products" rather than "Download Documentation". Choose your version and you will see the documentation links below the executable files. The only updated docs for 6.7.1 are release notes, supplement, and WorkflowModeler.
