Sometimes, i need to share my assets with some designers who don't have the latest version of your software (CS6 for example)
CS6 perpetual is a problem. CS6 products do not know about all that modern sharing stuff. As for the rest...they should upgrade to the latest CC version (or a major version down at most). Ideally, you should all be on the same level.
