The game's 2006 architecture struggles with the file-handling protocols of Windows 10 and Windows 11.
The "Save Failed" error in Hitman: Blood Money is a classic case of a great older game clashing with modern OS security features. The fix is rarely due to a corrupted download but almost always due to the game lacking permission to write to its own files. By granting "Full Control" to the Profiles folder, running the executable as an administrator, and crucially, disabling "Controlled Folder Access" in Windows Security, you should be able to eliminate this bug permanently. Good luck, Agent 47. Your silent assassinations should now be properly recorded for posterity.
Beyond the design choice, true technical failures often occur on modern Windows systems due to permission restrictions:
Because the Steam Deck runs Linux, you generally do not need "Run as Administrator," but you must ensure the SaveFiles directory exists inside the Proton virtual C: drive.

This is the most common fix. By forcing the game to run with elevated privileges, it bypasses the UAC block on the Program Files folder.
Saves created on a "folder" memcard often fail to load 0.5.1. Go to > Memory Cards .
David stared. He hadn't pressed 'Continue' in the menu. He hadn't pressed anything. The cursor hovered over 'Yes' by itself.
