The Connexion client reinstallation attempt on the user's side is being caused by the Microsoft MSI self-heal technology attempting to fix what it perceives as a damaged installation.  The installation is fine.  To resolve the problem we need to build a new desktop shortcut.  To do this:

  1. Close Connexion client if it's running.
  2. Hold down the Windows key (to the left or right of the Alt key) and while holding it down, press the letter r; this brings up the Windows Run box.
  3. Type c: (including the colon (:)) and press Enter.
  4. Double-click (if 64-bit) the Program Files (x86) or (if 32-bit), Program Files folder.
  5. Double-click the OCLC folder.
  6. Double-click the Connexion folder.
  7. Double-click the Program folder.
  8. Scroll down and right-click Connex.exe and choose SendTo > Desktop (create shortcut) (If you don't see the .exe extension, look in the 'Type' column for 'Application').
  9. Double-click the new shortcut.  The client should start normally.
  10. Delete the original desktop shortcut and rename the new one to look like the one you just deleted.
