Hello Klaus
This stargo.exe is a temporary version, released to add this feature requested here from Avalon Instruments users.
The StarGo notice to upgrade the firmware to the 6.4 because that will be the next firmware version number. In this moment you don't find the firmware 6.4, because it will be added when the next StarGo SP version will be released.
So for the moment don't pay attention to that message, just click on the "x" button and keep using the StarGo.
Let us know about.
Best regards
Stefano
Avalon Instruments Team
