After a successful installation, the first time a tool is launched, it will prompt for the serial number and licence key. See Intializing the tools.
If the box reappears then the key was not accepted double check that the shorter serial number is entered into the first field on the top and the longer product key is entered in the lower field underneath.
Check that the key you have entered matches the version installed. We issue new keys for each major and minor release so a key from a previous version will not unlock a newer version.
We send keys to the licence holder nominated for licence. Please contact them to obtain the latest keys for your organisation.
