What do you mean by disable all in both sections?  Will I need to enable them again once I get the path installed?

I have been getting this error as well.  I recently decided to re-install the game and when I try to install the patch, the error pops up.  After manually uninstalling everything, I sent an email to EA.  They have suggested saving the game in another file, saving the launcher in another file, and creating another account on my computer and installing the game there.  None of that has worked though.

Along with this, I also cannot download the items I bought in the store or Riverview but I can download items from the exchange.  I have found sites that have the old patches and cannot download those either.  If anyone has any ideas on how to fix this, I would really appreciate it.

Edited to add:  I can install and play the game, just not with the patch.
