Installer won't let me install TS4 on D:\ + Origin problems

So, I downloaded G4TW's TS4 for my boyfriend and his computer has a partitioned hard disk, so he installed the OS at C:\ and every other program such as games and etc at D:\, but everytime I try to install it on his computer it shows this message (it's in Portuguese, I'll translate it):


(Trying to install at D:\)


(Basically says that C:\ doesn't have enough space even though I'm trying to install it at D:\)

And when I installed it on my computer (regular install at C:\) everything went fine, I applied the ultimate fix, but when I try to run it, a message saying that Origin must be on to run it. So okay, I opened Origin, but the message keeps showing.

Does anyone know how to fix this errors?

You can't install on D: through the installer, no matter what you chose, it will be installed on C. However, you can move it to another drive after you're done with an install, check this guide.

The point of crack is to avoid Origin's DRM, so if the crack is working correctly, there's no reason as to why it would ask you for Origin. Make sure your crack isn't getting removed by your antivirus software. And also make sure Sims 4 isn't getting blocked by firewall, it gets some packets from sims4cdn.

The disk change worked just fine, thanks btw. But now both computers get the origin message... I'm starting to feel really annoyed by it. It worked once on his computer but the second time he tried to play it the origin message started popping up. I tried everything: uninstall, download the ultimate fix again, nothing worked. I put the TS4 installation folder on avast's exception list and it didn't work either. Tried to open Origin and go offline... nothing. Really starting to give up.
