Hey SuperNinja,

These issues can happen for several different reasons. If you have any antivirus or security software, you may want to disable them temporarily to test the install.

I’m having the same problem, I had bnet installed previously however I had to uninstall it and all of the related files because according to the help threads that’s the only way to fix not being able to install/update/or run COD MW. I tried to reinstall but immediately got " BLZBNTBTS0000005D"
Now the terrible interface for the forums plus the terrible support is making it impossible to figure out what to do.
Good luck I guess, just a shame that I wasted money on a service that used to be about gaming and is now about patting China’s back.
