The DirectX Offline Installer (historically named dxwebsetup.exe when online, but the full redistributable is often called directx_Jun2010_redist.exe ) is a standalone, self-contained package that installs legacy DirectX 9.0c, DirectX 10, and DirectX 11 runtime components. Microsoft’s modern Windows operating systems (Windows 10 and 11) come with DirectX 12 pre-installed, but many older PC games (from 2000–2015) require older DirectX DLLs like d3dx9_43.dll , xinput1_3.dll , d3dx11_43.dll , or XAudio2_7.dll . The offline installer ensures these files are present without needing an active internet connection during installation. Why Use the Offline Installer Instead of the Web Version? | Feature | Web Installer ( dxwebsetup.exe ) | Offline Installer ( directx_Jun2010_redist.exe ) | | ------- | -------------------------------- | ------------------------------------------------- | | Internet required | Yes (downloads only needed files) | No (all files included) | | File size | ~300 KB (launcher) | ~100 MB (full package) | | Best for | Single PC with stable internet | Multiple PCs, LAN parties, retro gaming builds, no internet | | Reliability | May fail if Microsoft updates links | Works identically every time | | Content | Same final result | Same final result |

Always keep a copy of directx_Jun2010_redist.exe on a USB stick or external drive. When you install an old PC game from disc or GOG offline backup, run this offline installer first — it will save you hours of hunting for missing DLLs.
