I'm having this strange problem when updating a version of Draftsight which was about 2-years old to the latest version.  When installing the latest version told me it could not uninstall the old version.  I went to Windows and uninstalled the version on my computer.  Now I keep getting the message in the subject line above.  Is there perhaps something left over in the registry that must be manually removed.  I'm running Windows 10 Professional
