Update button Audirvan fails

Dear Damian,
The Audirvana version update button on my desktop pc doesn’ t function anymore, but i can still update by the old way by restarting the software again.
On my laptop update proces via the button is okay.
Both ps’s have Windows 10, on desktop it is 64bit pro and the laptop has a 64bit standard version installed.
Both pc’s Windows are fully updated to 1903.
Please let me know what is best to do, or is it a bug in Audirvana?
Best regards,
