VMware tools upgrade to 10.5 causing major outage ?

Hi People,

When performing the previous VMware tools upgrade, I usually don't expect to do any major outage at all, normally only 1-2 ping packet loss. But today it has caused my some big issue where the production terminal server patch network adapter lost (not appearing in Network adapter folder) ?

The VMware tools was upgraded from earlier version to the latest v10.5 by double clicking on the setup64.exe file and it was taking so long time stuck in VMXNet3 driver update. eventually it finished successfully with the below error logged:

Therefore I have to perform reboot which cause some grief and frustration from the users !

Can anyone please assist me in troubleshooting what the root cause of the issue as the management and the change management team now demands some explanation from me ?

Please help me.
