An issue that’s proven to be rather common with web browsers is controlling which email program is ran when you click on an active email address on a website. If it’s not properly configured, then you will be presented with the “Default Mail Client Is Not Properly Installed” error message.
If, while surfing the internet, you clicked on an active mailto link or a link that should load up your default mail client and received that error message, then you’ve come to the right page. In Windows it’s possible for you to manually set the default mail client for specific tasks. In a situation like this, you should already have a default mail client configured, which will load up as a result of you clicking on the link. However, if you don’t have a default mail client set or if vital Windows services have been disabled and/or corrupted, it can result in the “Default Mail Client Is Not Properly Installed” error message.
There are a number of mailing programs that you can set as your default and there are so many instances when you may need one. With that said, there are also equally as many instances when that error may occur. In most cases, when a user clicks on an active link or a mailto link, the mailing application that has been set to default will load up. If the specific mail client that has been set to default is properly configured, then it should load up automatically inserting the corresponding email address into the send to box. When the reverse is the case, you’ll receive the error message; however, this is not the only reason why you may be confronted with this error.
Common Causes of This Error
The vast majority of the time, the default mail client is called up due to actions taken while surfing the internet. The configuration settings for your default mail client are managed by your various internet browsers and also by your operating system. This configuration data is thus held within the registry. The registry is basically a database system used for storing all Windows configuration data, thus, should the data on your default mail client be invalid and/or corrupt, the associated program will fail to launch. Below are some of the more common causes for this particular error.
- The Windows registry has become corrupted.
- No default mail client has been set.
- There’s a conflict between the various mailing applications on your computer.
- The default mail client has been configured incorrectly.
The vast majority of the time, this error is due to an incorrect configuration; however, registry corruption is also a reality, so you should keep that in mind. For a guide on how to troubleshoot this error, continue reading.
Manually troubleshooting this error may not be to everyone’s liking, fortunately for such people, there is an alternative. As was mentioned earlier, although an incorrect configuration tends to be the main culprit, there’s also that chance that there may be a conflict within the Windows registry. For the average computer user, it’s important to note that making modifications to your registry is a very dangerous procedure. This is why the automated approach is so popular.

Windows Vista/7 Users
One thing you must keep in mind is that Microsoft Outlook Express has been superseded. So if you upgraded your operating system from Windows XP to Windows Vista/7 and you brought this mail client over with you, you will be unable to use a vast majority of its features, due to it being incompatible with these versions of Windows. So if the error you’re receiving is due to this application, you may have to run a repair installation of Windows to fix it.
To do that, I’d recommend you used Reimage, which is a Windows repair tool, capable of repairing your Windows installation, without the requirement of a Windows CD, on the fly. It’s a very easy tool to use that is designed to repair a plethora of error types. Anyway, for more information on this tool, visit the following link: http://www.compuchenna.co.uk/go/reimage
However, if you’re using Microsoft Outlook Express in a Windows XP environment, then the information in this guide should be sufficient in rectifying your issue.
