OK I downloaded and installed CCP, I used it to create a "Package", and then I ran the setup.exe that's in that package. It finished in about fifteen minutes, but it hasn't actually installed anything.
If I open "Creative Cloud" it now gives the option to install all the apps; select one and it starts downloading it.
So this is just the same process as going straight to the CC web site and downloading from there. So far I do not see where CCP is adding any value.
Is it not possible to download the install package(s) once and store them on my network, then run setup from there? Downloading Gb's for each and every workstation cannot be the answer I hope.
