i just tryed to install the update through the vCenter management web page, even with the mountet ISO i get:
Tomorrow i will test via CLI...
The update to 7.0.2a has worked without problems.
I always prefer cli after mounting the ISO.
Interestingly I tried the online way in my 7.0U2a lab and saw this for few seconds. I see that message everytime I login but goes away after a min or so. Once message vanished; I was able to click on check for updates and install it though
