Windows 7 - Application download did not succeed

Application download did not succeed. Check your network connection, or contact your system administrator or network service provider. That what a family member of mine gets when they try to download anything off of the internet. Its old probably running windows xp or older. Anyone know what the problem is and how to fix it, hits on Google dont explain, only for this one click thing

I know this is windows 7 forum but maybe it pertains to us also

Come on

Could you please give more information on the issue: operation system of that computer, browser, may be some error codes? What type of content is being downloaded, what website?

Screenshots actually would work too.

its not my pc but im trying to work on it remotley. No downloads at all are possible. Its windows xp and internet explorer

I understand. But, still more info is required:
How all this started?
Is that a home computer or office?
Was it always like that or let's say installation of some other software triggered that?
Please also check if user has Administrative rights using this tutorial.

Also, just a suggestion: have your relative tried any alternative browsers like Firefox, Chrome, Opera?
