I own Indesign cs6 but have a client who uses cs4. (saving to idml is problematic so am trying to figure out a way to solve this) I will upgrade to CC soon but I understand that it will not allow me to use older versions. I have downloaded a trial cs4 for now, but when it runs out what can I do? My client doesn't need to upgrade so I doubt they will. I don't suppose my cs6 serial number will work at the end of the cs4 trial or will it? Seems like there should be some way to do this if I have bought later versions but signs point to no. any thoughts? thanks. L
Why is it problematic to save to IDML? That's the only solution I know.
