File associations

The last app installed controls the file associations. For example, if Office 2019 was installed last, Office 2019 applications will open an Office file by double-clicking it..

The file extensions can’t be associated with Office 2007 if you haven’t installed the latest Office 2007 updates through Windows Update. Without the latest Office 2007 updates, if you right-click a file, and choose Open With, you’ll only see the latest version of Office installed on your machine.

You’ll also only see Office applications associated with the latest version of Office on your machine listed in Control Panel under Default Programs.

Outlook 2007 won’t start after installing Office 2013, Office 2016, or Office 2019

After you install Outlook 2013, 2016, or 2019, Outlook 2007 won't start, and you get the following error:

Cannot start Microsoft Office Outlook. Unable to open the Outlook window. An OLE registration error occurred. Ths program is not correctly installed. Run Setup again for the program.

So you'll need to only use newer version of Outlook.

File sharing uses Outlook 2013, 2016, or 2016, and not Outlook 2007

When you try to share a file using an Office 2007 application using File > Send, Outlook 2013, 2016, or 2019, will start and correctly attach the document to an email.

Open files from Office 2007 with Office 2013, 2016, or 2019, on the computer

Open the application version you want, and choose File > Open. There is no way to open some documents with 2007 and some other ones with 2013, 2016, or 2019 because the file associations are controlled by the newest version.

Office 2007 most recently used list are not the same as Office 2013, 2016, or 2019

Newer versions of Office (2013, 2016, or 2019) have a shared most recently used feature that travel with you from device to device when you're signed into your Microsoft Account. But Office 2007 didn't have a shared most recently used list, so each Office 2007 application has its own list and specific to the device its installed on.

Custom shortcuts to Office 2007 applications won’t be updated

Office 2013, 2016, or 2019, doesn’t know about any shortcuts you created to the older applications and won't update them to point to newer version.

For example, after you installed Office 2007, you pinned a shortcut for the 2007 version of Word, Excel, and PowerPoint to the taskbar and to the Start menu. After installing Office 2013, 2016, or 2019, these shortcuts still open the 2007 applications.

Shortcuts to Office applications added to Windows taskbar

If you have a shortcut to Office 2007 that you created and you uninstall Office 2007, the icon will become a generic icon.
