I'll admit that I am just getting my feet wet in creating extensions of any sort. However I wanted to try to create an extension package that would deploy a script and a panel that would run a script. I packaged my .jsx file as well as my exported panel using the Exchange Packager. This was not to through the online exchange, but rather for my clients to use. It installed fine for me, but when I install it on a machine with CS5 or earlier it says that it requires CS6.
I understand that you guys are probably pushing the Online Exchange, but what's the best way for me to package files like this to make it easy to deploy? I saw the manual for how to package manually, is that what I should be doing?
