Problem with Outlook 2007 after uninstall Office 2013

Dave Doerner 21 Reputation points

I have been using Outlook 2007 on Windows 7. I installed Office 2013 to see if it would fix a problem I was seeing but it did not. So I uninstalled Office 2013. Office 2007 works except when I invoke Outlook (2007) I see: "There is no email program associated to perform the requested action. Please install an email program, or if one is already installed, create an association in the Control Panel under Default Programs."

I invoked Default Programs but Outlook 2007 is not listed in the Default Programs control panel to create an association with.

I tried deleting the Registry entry for HKEY_LOCAL_MACHINE\Software\Clients\Mail\Microsoft Outlook, and then doing a "Uninstall -> change -> repair" on Office 2007 but got message that configuration failed. Running diagnostics in Outlook 2007 did not find anything to fix.

I'd rather not uninstall Office 2007 and then reinstall it but can't think of anything else to do. Any suggestions?

    Hi anonymous userDoerner-1014 ,

    Welcome to our forum!

    As I know, support for Office 2007 ended on October 10, 2017, which means that you'll no longer receive Office 2007 software updates from Microsoft Update or security updates and no further updates to support content will be provided. It's suggested that you could upgrade to a newer version of office for a better user experience.

    According to your description, I noticed that you have deleted the Registry entry and fix Outlook program but they didn't work. Since Office 2007 is no longer supported, I can't test in my environment. Through my research on my research, I find a similar thread with yours which mentions that Outlook 2007 works after he uninstall and reinstall office 2007. I notice that you don't want to use this method, but I'm afraid it's a better suggestion to try at present.

    No, reinstalling Office 2007 is the way to go to repair your installation. As you can only have 1 version of Outlook installed at a time, installing Office 2013 with Outlook automatically uninstalls any previous version of Outlook.

    That said, wouldn't you rather focus on solving your original problem instead of continue to use Office 2007? Outlook 2007 has been out of support for quite a number of years now (since October 2017) and is vulnerable to several known security issues which are actively being abused as well. Office 2013 will receive security updates until April 2023.
