I would to upgrade my veeam installation from 12.3.2.3617 to veeam 13.1.
But each time I try to upgrade, I have an error message like
<TBD>Signature verification failed after retries for 'C:\ProgramData\Veeam\Setup\Temp\e592ef21-b044-4aa4-92fe-548a234f7856\cea2c8a9-c262-4fd8-b61e-1003527a2929\CoreWCF.ConfigurationManager.dll'.
Signature verification errors usually mean that your machine does not trust the signing certificates we used. I recommend making sure that your Windows machine is fully updated via Windows Update, and then trying again. If the same error occurs on a fully updated machine, you must work with our support team to resolve the issue.
