OS: W10 EDU 19044.1766 (21H2)
LV: 2016 / 16.0f7 (32bit)
After a recent fresh install of LV the update manager did install some updates, so in principle it seems to work.
It showed patch "F5", but that was not installable, supposedly a download error. More info below.
I manually downloaded patch "F7" and installed that just fine. I'm just interested in "critical updates", as we must remain with the current major version of LV.
A couple of screenshots for illustration:



The last error message translates to:
"An error occured in the NI Update Service while downloading one of the selected updates. Try again later or contact support."
Are there any logfiles indicating what and why has failed?
