With the October 16, 2018 patch we will be ending support for DX9 and the 32-bit version of the Heroes of the Storm client. DirectX has had several major releases since DX9, and the vast majority of players in the Heroes community are now running the 64-bit version of the game, along with DirectX11 or higher.

This means that the Heroes of the Storm client will no longer run for 32-bit users Please also note that while the 64-bit Heroes client might still be playable on some machines using DirectX10, this may not be the case for all configurations, which is why we recommend that all our players upgrade to at least DirectX11.
