I have Vista Ultimate and am using Thunderbird mail client. When I click a
mailto link in Internet Explorer I get this error message: "Could not
perform this operation because the default mail client is not properly
installed". I have reset my default programs, uninstalled and reinstalled
Thunderbird, and switched my default mail client to Windows Mail and still
the same result. On searching the web I can only find solutions for Windows
XP, Outlook and Outlook Express. Anyone know what the deal is with Vista
and Thunderbird rendering this error? And BTW I have the same setup on
another computer and the mailto links work fine.

Try the steps shown on page 3 of the May 2008 newsletter on this page:

Hi everyone,
I've spent the past few days trying to figure out why I see the message
"default mail client not properly installed" , when I click a "mailto"
link in FF3 or IE7. I was searching google and reading forums, and
editing lines in the "about:config" settings in FF3 and TB2, and even
using the regedit in Vista, and I don't have a lot of experience in
this, so luckily I didn't mess anything up.

HOWEVER,

I found a quick/easy solution to this.

Go to Control Panel --> Default Programs. Instead of clicking "Set Your
Default Programs", click "Set Program Access and Computer Defaults."

Click the Down Arrows on the right hand side for the "Custom" Row.

INSTEAD OF clicking "Use My current Web browser/email-client, click on
use FF, and use TB, and check Enable Access to this program.


All I know is that I had clicked "Set your Default programs" dozens of
times and tried that, but when I tried this "set program access and
defaults" and tried this method, my mailto links worked like a charm.
