If you don’t care then double click on it it will run it locally in Wine local prefix.
But if you play the game through Steam Proton then it will not help.
Note that you need to modify the {YOUR USERNAME} parts, and the path to the executable you want to run in your game prefix /path/to/your/file.exe. In theory the WINEPREFIX path should be good if you installed your game in the default Steam path.
Copy paste in terminal after modifying it properly, and return the result.
Change /path/to/your/file.exe with the proper path of the executable Watch_Dogs2-ScriptHook-Installer_r147.exe you want to install in your Proton prefix. //home/(me)/.local/share/Steam/steamapps/common/Watch_Dogs2/bin is definitely not the executable you have wrote in your command (and it has a double forward slash which is not good too).
this is one line full command, do not remove any part of it
replace the two {YOUR USERNAME} with your current user name
replace /path/to/your/file.exe by the full path of Watch_Dogs2-ScriptHook-Installer_r147.exe on your system
Can’t be more explicit than that Fires. It should run the executable Watch_Dogs2-ScriptHook-Installer_r147.exe in your Steam Proton prefix, then you install it as if it were Windows system (follow the installation note for this script hook thing you’re trying to install).
I know, I still want the user to write a proper path manually. If the user can’t understand what I’m asking for then I don’t see the benefit of introducing higher end commands, automatism and what not when he doesn’t even understand the basics. You think it helps I don’t. Sure it removes one possible error in the command, but in the end if you spoon feed every aspect of helping people they are just parrots and don’t learn anything.
That’s not complicated what is asked here, if user can’t keep up I’m out anyway so you could have fun.
Instead of reinstalling games in Steam, first approach would be to verify the game files in Steam this way if Steam find a corrupted file it will download it again, in case of bad installation it saves up lot of download time.
I would never fully uninstall/reinstall a game unless I’m out of ideas and tried everything possible to troubleshoot my installation as often games are between 10GB and 50GB so with my bandwidth it is a no no.
Anyway I don’t know why YOU would reinstall the game here, as there was no issue with the game, right?
