--- Comment #24 from themainliner themainliner@hotmail.com --- I used Lutris to manage my wine versions in parallel.
1. Created a fresh (64-bit) wineprefix: "~/.HotS64" 2. WINEPREFIX="~/.HotS64" winetricks d3dx11_42 d3dx11_43
Launced Lutris: 3. Used 'Install runners' on the 'Game info' tab to install other Wine versions. 4. Set 'Wine' as 'Runner' 5. 'Game options' tab: pointed Lutris at 'HeroesSwitcher_x64.exe', and the new Wine prefix 6. under the 'Runner Options' tab select 'Wine version': 'staging-2.15-x86_64'
If there is a cleaner, manual of installing *extra* versions of Wine side-by-side please point me at resources for that. I used Lutris simply to manage this (I also used PlayOnLinux without useable results).
