The fix for this turns out to be simple - see this blog post for details.

From the registry, when you see two keys under:

HKCR\TypeLib\{00020813-0000-0000-C000-000000000046}\

delete the highest one. In my case this was 1.8, but it will depend on your version of Excel/Office (the artical describes deleting 1.7). This problem does seem to return after some time (maybe after patches), so you may have to re-apply this fix unfortunately.
