1] NETWORK-FAILED error message
When you try to install something from the Chrome Web Store and see “NETWORK_FAILED” error, remove the unwanted software. Then, try to install the app, extension, or theme again.
If you still can’t install the app, extension, or theme, uninstall the browser and try reinstalling it.
2] No file or File missing error message
This error indicates that the file you’re trying to download either doesn’t exist on this site or has been moved to another area of the site.
To fix it, contact the website owner, or try to get the same file from a different site.
3] Virus detected or Virus scan failed error message
The error message itself is self-explanatory. If you have an anti-virus software installed and running then, it might be interfering with the download. As such, check your virus-scanning software for details about why the file was blocked.
The Windows Attachment Manager could have removed the file you tried to download. There are several features of the Attachment Manager that can be configured by using Group Policy or the local registry.
To see what files you can download or why your file was blocked, open Control Panel > Internet Options > Security tab. Here click the Reset all Zones to default level button, click Apply/OK and exit.
4] Insufficient permissions or System busy error message
If Google Chrome is failing to download any files, giving an insufficient permissions error, it means Chrome couldn’t save the file to your computer. Fortunately, there’s a simple fix.
Cancel the download and try again.
Secondly, rather than clicking the download link, right-click the link and select Save link as.
5] Needs authorization error message
This Needs Authorization error message seen in Chrome means you don’t have permission to download the file.
To solve this issue, contact the website or server owner, or try to find the file on a different site.
