That worked perfectly,thanks

I guess files from a previous version weren't deleted properly by Steam and f~~ked up the game,but now that they're gone I have no issues anymore

Thank you a lot for the help

Steam version.

Here's the error log for one launch attempt,if it helps
[2019-Dec-25 21:17:58 UTC] D:\Steam\steamapps\common\Warhammer 40000 Gladius - Relics of War\Binaries\Windows-x86_64\Gladius.exe --steam

Done,I was already running it as admin by default,still I reproduced these steps you gave me,but I'm still getting the exact same two error messages

I'm installing from Steam btw,is that an option steam gives you? I uninstalled again to check but I don't see anything like that.

Is there another executable I can get to install the game manually?

I did.
Just tried again openning Gladius.exe and Autorun.exe as admin manually,but same problem happens

Update : I fully uninstalled and reinstalled the game,but the problem persists

Second part of Dxdiag,was too long to fit in one post
