Veeam One 8 Server upgrade Fails because of McAfee

[Naith]

I had this error when trying to Upgrade Veeam One from V7 to V8.
"Failed to configure WEB Server 0x80070020"
In another Post I found the Problem is McAfee AV.
So if u use McAfee, before Upgrade to Veeam One 8 disable McAfee services or the Upgrade probably fails.

Thanks for sharing the solution. Is there any way to add Veeam processes to exclusion list in McAfee?

There certainly is but I didn't.
As far as I can say until now it is safe to disable the Service only during the Upgrade after that you can enable McAfee services again and everything works fine.
