Good morning

On some Windows 10 and Windows Server machines, I am getting errors with WUA.
Last error status: ValueError: time data '' does not match format '%m/%d/%Y'

Is this problem fixed in the latest version of WAPT?

Logs for the Install Windows Update task:

Hi Sébastien,

oops, I think there's a bug here. It seems that neither Windows Update nor WMI has any information about the installation date. This can happen if you deleted the C:\Windows\SoftwareDistribution\ folder and there's another bug at the same time, like the one we just encountered.

We'll look into it tomorrow at the office.

Best regards,

Denis

Hello,

just so you know, the c:\windows\softwaredistribution\ folder is indeed present on the affected machines.
Have you identified a workaround for this problem?
