Installing Parallels Desktop 11 with Error "Your Mac must be connected to the Internet to proceed"

I am trying to install Parallels Desktop 11 on my Mac (OSX Yosemite Version 10.10.5). I have already done the registration and logging in, and when i reached the page for activation and I clicked on "Try Free for 14 days" I encounter this error "Your Mac must be connected to the Internet to proceed".


I have followed the steps here as mentioned in the post here but I am still having this issue.
This is how my proxy page looks like:

And my host file:
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost

I have also downloaded and run Fix hosts for PDfM.zip (nth seems to happen after i run it) as described in the link and restarted by computer. Still, the problem is not fixed.

Help pls... thx...

 

Hi WeeL,
If you have any anti-virus software like Kasperky or Norton installed on your Mac OS, try disabling the anit-virus for few minutes and then try to activate the product and see if you are able to activate it successfully.

 

Hi, this is what I alr tried but it doesn't work (which is also mentioned in my post).

 

Yes I have avast installed. Disabled alr still doesn't work

 

Could you please try un-installing the anti-virus software and check how it goes.
