Unable to open this Internet site when you try to download an attachment in Internet Explorer 8

After I used CCleaner, I was unable to download attachments with Internet Explorer 8 (IE8).
CCleaner normally only deletes unneccessary files and registry keys. However, in this case it seems that CCleaner has cleaned a little bit too much :)
The following error occured when I tried to download a file with Internet Explorer 8:

Unable to download attachment.zip from www.webaddress.com
Unable to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later.

Unable to open this internet site at attachment download

I got this error when I left-clicked an attachment url, as well as when I right-clicked a link and chose Save Target As…

Solution:
In my case, I solved the problem by disabling some suspected add-ons. This can be be done as follows:

  1. In Internet Explorer 8, click Tools at the upperright corner
  2. Click Manage Add-ons
  3. Click Toolbars and Extensions
  4. Click any Add-on that you don’t know or trust, and click Disable at the bottom right corner. You can always Enable the add-on again. (as I want to make clear that you don’t permanently delete the add-on by only disabling the add-on)
  5. Restart Internet Explorer 8 and try again to download an attachment

Possible other solutions:

  • Some people cannot download attachments from within their Webmail. This is particularly the case with Yahoo Mail. You should switch to the classic Yahoo mail to work around this problem.
  • If you have McAfee Security Center installed, you should disable the SiteAdvisor.

If the site you’re downloading from outputs any “Cache-control” headers you will likely get the message. On my site I deleted those headers and downlaods worked fine with IE8.
