Some update manifests use $(runtime.syswow64) as an explicit target for the 32-bit system directory. wusa currently handles runtime.system32 with WoW64-aware redirection, but does not recognize runtime.syswow64, causing expression expansion to fail. Map runtime.syswow64 to CSIDL_SYSTEMX86 on x86_64, matching the existing runtime.programfilesx86 and runtime.commonfilesx86 handling. -- v3: Revert "wusa: Split cabinet path before calling FDICopy." https://gitlab.winehq.org/wine/wine/-/merge_requests/10748
