Cannot Associate Oxygen XML Author With a File Type on My Windows Computer

Problem

I cannot associate the Oxygen XML Author application with a file type on my Windows computer by right clicking a file in Windows Explorer, selecting Open With > Choose Program and browsing to the file oxygenAuthor20.0.exe. When I select the file oxygenAuthor20.0.exe in the Windows file browser dialog box, the Oxygen XML Author application is not added to the list of applications in the Open With dialog box.

Cause

The problem is usually due to old Windows registry entries remaining from previous versions of Oxygen XML Author.

Solution

Uninstall all your installed versions of Oxygen XML Author and reinstall your current version of Oxygen XML Author. If you only have the current version installed, you could try to reinstall it without uninstalling it first.
