Bug ID: 56795 Summary: Windows version is detected as outdated by XboxInstaller.exe Product: Wine Version: 9.10 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: kernel32 Assignee: wine-bugs@winehq.org Reporter: tobil4sk@outlook.com Distribution: ---
The Xbox App installer has a minimum requirement of Windows 10 19H1 or higher. However, even when the version is set to 10 or 11, the app shows a message saying that the version is outdated and that an update has to be performed before the installer can run.
The GetVersionExW() function in dlls/kernelbase/version.c is returning version information for Windows 8 instead of 10. This happens because of this line in init_current_version, where the RtlImageNtHeader has the version 4.0 so it defaults to Windows 8 as the reported version. https://gitlab.winehq.org/wine/wine/-/blob/951e0e27a743e52c75c7fedc0b1eaa9eb...
This looks intentional, so maybe the real issue is that the IsWindows[x]OrGreater functions are missing from wine.
Note, it is only possible to start the app without crashing if this patch is applied: https://gitlab.winehq.org/wine/wine/-/merge_requests/5771
