You can't install stuff via the launcher if you have awesomemod installed, took me a bit of fiddling to figure that out myself. I changed my awesomemod, awesomemod config, and resource.cfg filenames so that they weren't loaded when the game started, then after I was done installing I closed the launcher, named the files back to normal, and started my game again. I'm not sure what you mean about all packages(unless you mean the .sims3pack files, not the .package files).
This question probably should have been posted
here, not in a whole new thread, just fyi.
