PhysX System software provides updates necessary for some games to run PhysX content properly
These URLs are the ones NVIDIA Corporation declares in its own manifest. We do not proxy or shorten them, and we do not host a copy.
Run this against the file on disk. If the output does not match the hash below, the file is not what NVIDIA Corporation published. Delete it.

Got a different hash, or one you cannot place? Paste it into the hash checker and it will tell you which program and version it belongs to, past releases included.
If a program reported one of these as missing, this is the package it belongs to. Installing it puts the file where it goes, registered properly, which downloading the DLL on its own does not.
The unattended switch below is the one NVIDIA Corporation declares in the installer manifest, not one we guessed by trying flags.

.\PhysX_9.23.1019_SystemSoftware.exe /sRun it from the folder holding the downloaded file, in a terminal opened as administrator when the package installs for all users. Silent means no window and no prompts, so check the exit code rather than waiting for something to appear: 0 is success and 3010 means it worked but wants a reboot.

Every guide on this tells you to hunt for the product code with Get-WmiObject or in the registry. You do not need to: it is published in the installer manifest, and it is printed below.
Product code · 32-bit
{B2FE1952-0186-46C3-BAEC-A80AA35AC5B8}_Display.PhysX
Uninstall, with the usual prompts
msiexec /x {B2FE1952-0186-46C3-BAEC-A80AA35AC5B8}_Display.PhysXSilent, for deployment
msiexec /x {B2FE1952-0186-46C3-BAEC-A80AA35AC5B8}_Display.PhysX /qn /norestartThe codes above belong to NVIDIA PhysX System Software 9.23.1019, the version in our index. If you have an older release installed, its code is different and this command will report that the product is not installed. In that case run Get-Package -Name "NVIDIA*" in PowerShell to read the code of what you actually have.
This removes the program as the publisher packaged it. Settings and files created after installation, typically under AppData, are deliberately left behind by the uninstaller and have to be deleted by hand if you want them gone.
Reinstalling and hitting error 1638? That is this same product code, and the command above is the fix.

Yes, in the sense we can actually verify: the installer downloads from nvidia.com, which is a domain we have tied to NVIDIA Corporation.
The installer on this page comes with the SHA-256 NVIDIA Corporation declared, so you do not have to take our word for it: hash the file you downloaded and compare.
What this does not tell you is whether the software itself is any good, or whether you want what it does once installed. A publisher can ship something you would rather not run and the download is still authentic. We answer the question we can measure and leave the other one to you.
If Windows says “Windows protected your PC” when you run it, that is SmartScreen reporting reputation, not a malware verdict — it shows up on perfectly legitimate software from small publishers and on releases that are simply new. The reverse matters more: no warning does not mean the file was checked.
How the 88/100 score is calculated · why the source matters more than the reputation
Windows ships with a package manager, and this program is in it. The identifier below is the one Microsoft's repository uses, which is also where the download URL and hash on this page come from.
Install
winget install --id Nvidia.PhysX --exactUpgrade later
winget upgrade --id Nvidia.PhysXWhy --exact: without it winget matches on name as well as identifier, and a search that returns more than one package makes it stop and ask rather than install. Pinning the identifier is what makes the command safe to put in a script.
Not installing anything, or getting an error back? The commands that actually come up covers upgrading everything at once, what --include-unknown is for, and why winget can be missing from a machine that should have it.
The version history of NVIDIA PhysX System Software, each release with the download URL the publisher declared at the time and the SHA-256 to check it against. Useful when an update breaks something and you need to downgrade to a build that worked.
We do not host any of these files and never re-upload them, which is the difference between this and an old-version download site.

Publishers take old builds offline without warning, so a link here can stop working even though the hash stays correct forever. If you already have the file, the hash is what matters: it tells you whether what you have is what they published.
Every NVIDIA PhysX System Software version with a published manifest, newest first. The most recent ones are listed above with their file names and hashes.
Matched on the categories NVIDIA Corporation and others declare in their own manifests, so the grouping is theirs rather than ours. Each one has its official URL and hash on the same terms as this page.
Not related to NVIDIA PhysX System Software — just other entries, each with its own official URL and published hash.
