NVIDIA PhysX System Software · earlier release
The URL NVIDIA Corporation published for this release, and the SHA-256 of every file in it, so you can prove the copy you have is that one and not something else wearing the same name.
NVIDIA PhysX System Software is now on version 9.23.1019. An older build stops getting security fixes, so install one only when you have a reason: a plugin that broke, a machine that cannot run the new one, a bug you need to reproduce. If you just want NVIDIA PhysX System Software, take the current version.
PhysX-9.19.0218-SystemSoftware.exe
Windows does this without installing anything. In PowerShell:
Get-FileHash .\PhysX-9.19.0218-SystemSoftware.exe -Algorithm SHA256
Compare what it prints with the value above. If they match, your copy is byte-for-byte the one NVIDIA Corporation published. If they do not, it is a different file, whatever it is called and wherever it came from. Paste a hash into the verifier and it will tell you which release it belongs to.
If PowerShell is blocked by policy on the machine, the same thing works from plain cmd with certutil -hashfile PhysX-9.19.0218-SystemSoftware.exe SHA256. On macOS or Linux it is shasum -a 256 PhysX-9.19.0218-SystemSoftware.exe.
Publishers retire old releases, and we do not host copies, so a link from an earlier version can stop working without notice. Two ways it fails: an honest 404, or — more confusing — the server answers normally but hands you the current downloads page instead of the file. If what arrives is a few kilobytes of HTML rather than an installer, that is what happened.
The hash on this page stays useful either way. It still identifies NVIDIA PhysX System Software 9.19.0218 wherever you find a copy, which is the whole point of publishing it: you can accept a file from somewhere else and still prove it is the one NVIDIA Corporation built.
