The package files ? You don't need to open them. Just copy into your mods folder. If they are rar files you need to donload 7zip or winrar.
Can you please help me to? I can't download cc either, when I try to it downloads a minecraft or photoshop file with the name of the cc I downloaded. What is the problem? Please help me
Seems the file type has been used by a different program. Have you tried just placing them in the mods folder?
You can change the default program:

But it should work the same with the other programs attached.
