Besides manifest files, SxS Loader can also take a config file similar to CLR apps which can instruct the loader to look for manifests in additional paths. Autodesk installers use this somewhat obscure feature so this probe path will help Autodesk software installer to start. The config file looks like ``` <configuration> <windows> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <probing privatePath="path"/> </assemblyBinding> </windows> </configuration> ``` Microsoft mentions this feature in [application config files doc](https://learn.microsoft.com/en-us/windows/win32/sbscs/application-configurat...). -- v3: ntdll/actctx: add correct fallback path using manifest.info actctx/tests: add tests ntdll/actctx: add proper probing functionality ntdll/actctx: add essential functions to read .config file and parse privatePath https://gitlab.winehq.org/wine/wine/-/merge_requests/10753
