I downloaded the steam version today in preparation to switch from win10 to steam.
After the steam version was done downloading, i started it to open the launcher in case it had any updates, there were none. So i clicked the big button to launch the game and received a "Cannot find 'd3dx9_43.dll'. Please, reinstall this application." error, and the game doesn't launch, even after i tried checking the box in the settings to not use directx9.
Normally in any other game this would tell me that i need to install or update directx9/10/11 etc. But the Windows 10 version still launches and plays without issue and I'm not entirely sure how to fix this. Not sure if this is a steam issue, a windows issue, a permissions issue, but it would sure be nice to fix it so i can finally switch to steam and not have both installed anymore.
