Q: hello, my Windows 7 browser often prompts “Default mail client is not installed correctly, so cannot execute the operation”. What to do then? The problem appeared after I uninstalled Outlook, as it always prompted the error dialog.
A: it’s quite likely that you uninstalled the Outlook component in MS Office, as Windows 7 already has no trace of Outlook Express, and Windows Live Mail download link takes the place of it. Your system problem should be caused because there’s certain file in system is broken. Suggest you reinstalling same version of Office Outlook, and then uninstall it to delete Outlook, then probably the problem could be solved. Besides, you can install and use Foxmail as the mail client, and set it as the default mail client of the system.
