Re: [PATCH 0/1] MR7705: setupapi: Respect ERROR_SHARING_VIOLATION from open KnownDLL file handles.

[William Horvath (＠whrvt)]

The section objects are created with `OBJ_PERMANENT` and a specific sharing mode (`FILE_SHARE_READ | FILE_SHARE_DELETE`) by wineboot, and it's done once for each prefix architecture (system32/syswow64). That permanent object is still open on the second go-around (next architecture), so when the setup tried to open that object with a different sharing mode, it ran into `ERROR_SHARING_VIOLATION`.

Refer to this documentation if that still wasn't clear:
