The xinput9_1_0.dll file is a library needed for using Xbox controllers and is by default included in Windows Vista but not in Windows Server 2008. This dll is needed to play several games like Grand Theft Auto IV, Halo 2 and more.
To install this dll I created a zip file including an batch installer that works on both the x86 and x64 editions of Windows Server 2008.
- If you are using the x86 version of Windows Server 2008, it will install the x86 version of xinput9_1_0.dll into %windir%System32.
- If you are using the x64 version of Windows Server 2008, it will install the x64 version of xinput9_1_0.dll into %windir%System32 and also the x86 version of this file into %windir%SysWOW64.

For those who want to get these files manually: you need to download the DirectX Software Development Kit, extract it somewhere and go to the Redist folder where you can find the x86 dll in the file Oct2005_xinput_x86.cab and the dll for the x64 architecture in the Oct2005_xinput_x64.cab file.
