Case #04832632 — Failed to install agent RPC function 'PckgCheckSignature

[michaelgunadi]

Not able to install agent remotely.

Error: Failed to call RPC function 'PckgCheckSignature': Signature of module 'c:\Windows\Veeam\Backup\Upload\.......' is invalid.

Tried already to install the certs according to kb2566: https://www.veeam.com/kb2566, still the same problem.

Hello,
and welcome to the forums.

As the forums are run mainly by product management, I can only recommend to continue with support on that issue. As the first assumption with KB2566 from support didn't work, further investigation of the logs is needed.

Best regards,
Hannes

Michael,

Any chance the target OS is running latest Windows 21H1? Thanks!

Hi Dima,
No, it's Windows 7 and I can't upgrade this station due to old application running on this computer need that OS.. not sure the compatibility.
