The Windows installer

At a glance

Running it

1. Open the download page and get the installer.
2. Run the file the way you would any other Windows program.
3. Accept the install location or pick your own, ideally on an SSD.
4. Launch Vesper when it finishes.

There is no account step, no activation, and no second download to chase. The launcher opens straight into its night-mode interface.

What gets installed

The emulator, the launcher interface, and its configuration files. That is the whole payload. No games arrive, no firmware arrives, and no toolbars or extra software are bundled alongside it.

Leave room on the drive for your own games as well as the app. Vesper itself is modest; the PS5 titles you add are not.

Check these before you install

• 64-bit Windows 10 or Windows 11. Windows on Arm, macOS, and Linux are not supported yet.
• An x64 CPU with AVX2. Without it the emulator cannot run at all.
• A Vulkan 1.3-capable GPU with a current driver.

All three are covered in more detail on the spec page, and the AVX2 requirement is the one that most often rules out an older laptop.

If the app will not start

A missing-DLL message at launch usually means the Microsoft Visual C++ 2015-2022 x64 runtime is absent. That is Microsoft's own official runtime, and the missing-runtime guide explains where to get it.

If the window opens and then closes, an out-of-date graphics driver is the next thing to rule out.
