I have tried moving iWork '09 from my clone (prior to wiping and installing Mavericks fresh), from my other Mac (updated to Mavericks using the in-place method, thus leaving iWork '09 installed), and finally from the iWork '09 retail DVD, then updating to 4.3. None of these three methods produces a Pages 4.3 or Keynote '09 version that will run. The install seems to go fine, but the app will not create a new document or open a document created by Pages '09 (or any other version).
Old (feature complete) iWork still runs fine on my MacBook, but I would really love to have it back on my iMac without having to revert to Lion. Is there an intricacy in the copy-over process I am missing or something I can try to track down that might be hanging my particular install? I've cleaned out all the .plst files associated with iWork that I can find. When I boot back in to the clone from last week (Lion), Pages 4.3 still runs normally, so it's not corrupted.
Thanks,
