Hello,
I’m attempting to run a 64-bit Windows installer using the Flatpak version of Wine (org.winehq.Wine) on AlmaLinux 9.
Despite granting full file system access via Flatseal (including $HOME and all system files), the installer crashes immediately on launch with a stack overflow error. The terminal shows:
err:virtual:map_image_into_view failed to set 60000020 protection on C:\\windows\\system32\\ntdll.dll
err:virtual:virtual_setup_exception stack overflow
I’ve tested multiple Flatpak versions of Wine (wow64-24.08, etc.), freshly initialized the Wine prefix, and even launched Wine via --command=bash to ensure environment control. The failure persists.
This same installer works under native Wine on non-Flatpak-based systems. It seems the Flatpak sandbox is preventing the memory protections required to load ntdll.dll properly under WoW64.
Questions:
- Is there a known workaround to allow Flatpak Wine to run 64-bit installers requiring executable memory mapping for system DLLs?
- Is this a known Flatpak sandbox limitation, or can the issue be resolved via overrides or manifest adjustments?
Thank you in advance for your help. In version 8 it runs without any problems.
Best regards,
Juergen
