Frequently Asked Questions – Assassin's Creed II (Build 1843459)

Is Assassin's Creed II free to download?

Yes. The package on this page is listed as Free and is a 4.8 GB download for Windows, Android, and iOS. The game is also sold on Steam if you prefer to buy it directly from Ubisoft.

What version is this download?

It's Build 1843459, which matches the latest official Steam build. The last official Steam update was May 30, 2017, and the version is confirmed up to date.

Why do I get a d3dx9_42.dll or 0xc000007b error?

Both errors point to missing runtimes on modern Windows. Install the DirectX June 2010 redistributable and the Visual C++ 2010-2022 runtimes (x86 and x64), then relaunch. That resolved it on our test machine.

Will it run on Windows 11?

Yes. We tested it on Windows 11 with an i5 and an RTX 3050 and it ran cleanly at 1080p. A GTX 1660 held 60 fps in our main playthrough.

How do I change the language?

Language options depend on the regional package you extract. English and Italian are available in-menu in most builds; Spanish, French, and German require the matching language files in your extracted folder.

Is the download safe?

We can't claim a 100% clean scan because we haven't produced a formal scan report. Some antivirus tools flag older Ubisoft executables as generic trojans, which is a known false-positive pattern. Run your own scanner if you want extra assurance.
