The first error is beacuse your license is for PGI Version 9.0 or earlier so needs to be regenerated.
As to why the license generator is failing, I’m not sure. It’s the first time I’ve seen this message and the person who wrote this program is on vacation so I can’t ask.
Do you mind using the online license generator? Log on to your PGI Web User Account (https://www.pgroup.com/account/index.php) and select “Create permanent keys”. After selecting your PIN, select “create license key” for the next available seat, and then press “continue”. You’ll need to know the hostname and FLEXnet hostid. You can get this information by running “lmutil lmhostid” and “lmutil lmhostid -hostname” from a PVF Command Shell.
If you have problems, you can send a note to PGI Customer Support (email@example.com or firstname.lastname@example.org) and they can better help you through the process.
