could not download an installer extension
Hi,
I have a Macbook pro with retina display. I restarted it today and now all the programs i downloaded since i got the Mac are all gone. (vlc media player/utorrent). I tried installing them again but it keeps giving me an error could not download an installer extension. My firewall is already disabled and my settings are on "allow apps downloaded from anywhere". I do not have any VPN software and have verified and cleared my hard disk. I don't have any apple support where i am 😟. Help Please !!
MacBook Pro with Retina display, OS X Mavericks (10.9.5)
