Google built one of the best Internet browser but I guess they forgot some issues in it. I faced a lot of difficulty installing it over the networked computer. If you have a computer where users log in to their own accounts, then Google Chrome has to be installed in each and every user account seperately.
My computer system is a networked computer and is behind ISA firewall and downloading executable files (.exe) are blocked by network administrator. This became even the worst problem. If the administrator logs on to his username on my PC, then chrome is only installed in his login, not mine.
Download Google Chrome Standalone Offline Installer from Google Website.
So, finally I found a Google Chrome Standalone Offline Installer. The network administrator downloaded it using his admin rights permission (which can download .exe file) and then I was able to install Chrome in my user log in.
