Google Chrome Installer Download Failure Error

Asked By 40 points N/A Posted on -


I had shared my recent problem of software on a different forum but got no answers. So this time, I am posting this question here because here, I see people do reply to questions. So friends, I have attached below the image of the error which I am receiving when I installed Google Chrome update.

Installer download failed. Error code = 0x800421f4

This error appears again and again when I run the update of the browser. I thought that there might be problem with my computer. So I tried the same update on a friend's computer. But  again, this error appeared. Now I am stuck here and can't further figure out why the update was not getting installed.  

So please, if anyone knows how to install this update or knows any other solution to it,  then please reply to this question.

Your computer firewall, anti-virus software or proxy might preventing your request. If this is the case, you need to add it to your security software's exceptions list. Please follow these steps when you are using Window's Firewall:

Start > Control Panel > Windows Firewall > Choose Exceptions tab > Click the Add Program button. Like this one:


  • Click Browse > Select My Computer > Select Local Disk (C) > Select Open
  • Open Documents and Settings > Open the folder with your username
  • Open Local Settings > Application Data > Google > Update
  • Select the folder with the highest number and open it.
