I got a few questions, asking for help out there.

Guys, little help...I gots a few questions before I do anything stupid.
...
Is it possible to install the game through a flash drive? Like transfer contents into the flash drive, plug it in the pc then click the ISO file?

And..

Do l need to have Origin installed or do the manual update instead?

Sorry for the trouble, I just don't want to cause problems on my dad's computer. :]
Thank you

on the first i can`t give you answer because i don`t know but on the second question ,you could do it both,or just origin or just manual, i do it manual my self (but have origin installed)

If you mean, have the installation files, like the rar that you downloaded, on the flash drive, and just install it from that, without putting those files on the computer, yes, that does work.

As for the second, Origin isn't required, though it can help fix a couple problems if you encounter them. Without it, all that will happen is you'll get a message saying the game can't connect to origin, and this could happen every time you play, or never. The manual patch is always recommended, because otherwise you have to replace quite a few files in order to update.

Hello,

Sorry for the late reply!
Unfortunately we were not able to get back to you in time. I'd like to apologize for that.

Do you still need assistance?
