dsetup.dll Vanishing???

[Aesthetics]

After no major system changes, from one day to another, I got the 'dsetup.dll missing' when launching. When I try to replace the file with the current p99 files .. they all copy, except for the dsetup.dll file extension. It also disappears from the extracted folder.


Things I've tried.

-reinstalling a ton.. before and after every other possible option.

-redownloading fresh p99 files

-creating exception through AV (windows defender)

-trying to move files on a diff user

-restarting

- getting a new version of the game

-change folder settings.

I'm running Windows 10



If anyone could please provide me with info that would be awesome
