How to Install and Set Up The Witcher 3 on PC

A practical PC setup guide for The Witcher 3, including upcoming requirements, storefront version options, file verification, and safe save backups.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Install The Witcher 3 through the PC storefront account that owns it, then use that client to update, launch, or repair the game. Before installing, check which version you plan to play: CD PROJEKT RED’s upcoming minimum requirements specify Windows 11, an SSD, and DirectX 12, but the studio has not announced when those requirements take effect.

Before installing: confirm ownership and check your PC

Use the PC storefront and account where you own the game. CD PROJEKT RED’s support materials cover Steam, GOG, Epic Games Store, and Battle.net. The normal route is to find the game in that client’s library and use its install and update controls; exact button labels can vary by client.

Check the upcoming minimum requirements

CD PROJEKT RED’s 2026 PC requirements notice lists the following upcoming minimums. These are stated requirements, not independently measured performance results, and the notice does not give an effective date.

  • Operating system: Windows 11 64-bit.
  • Storage: 70 GB on an SSD.
  • Memory: 12 GB RAM.
  • Processor: AMD Ryzen 5 2600 or Intel Core i5-8400.
  • Graphics: NVIDIA GeForce GTX 1660 or AMD Radeon RX 5500 XT 8 GB, with 6 GB VRAM.
  • Graphics API: DirectX 12 exclusive operation under these requirements.

CD PROJEKT RED says the game may continue to run on Windows 10, but the studio will no longer develop or test on that operating system and cannot guarantee future compatibility or performance. Its notice says: “That doesn’t mean that the game will stop running on Windows 10 with the next game update.” This refers to the upcoming requirements transition; it is not a promise of ongoing Windows 10 support.

  • Play as a highly trained monster slayer for hire.
  • Built for endless adventure, the massive open world of The Witcher sets new standards in terms of size, depth and complexity.
  • The Witcher 3: Wild Hunt Game of the Year edition brings together the base game and all the additional content released to date.

Install and launch the game

  1. Sign in to the storefront account that owns The Witcher 3.
  2. Open the client’s game library, select The Witcher 3, and use its install control. Choose an install location with enough space for the game.
  3. Allow the storefront to download and update the game before launching it from the library.

CD PROJEKT RED’s current support materials focus on launcher-based installations and recovery. The older PC manual describes an original disc installation, so its steps should not be treated as current instructions for Steam, GOG, Epic Games Store, or Battle.net.

Should you use the current version or Classic?

The latest version is the one CD PROJEKT RED identifies as fully supported. Choose Classic only if you have a specific compatibility reason, such as needing an earlier build for a setup that depends on it; older versions can differ in compatibility and content. The support information does not provide a complete feature-by-feature comparison of builds.

Storefront How to choose Classic Earlier version availability
Steam Open the game’s Properties and select CLASSIC under BETAS. Classic is documented as available.
GOG Open Manage Installation → Configure, select the Classic beta channel, disable auto-updates, then choose the version. Classic is documented as available.
Epic Games Store No rollback route is documented in the cited support article. Only the latest version is offered, according to CD PROJEKT RED.

DirectX 11 or DirectX 12?

Use the DirectX guidance for the particular build you are installing. The old PC manual says DirectX 11 is necessary for the version it covers. CD PROJEKT RED’s upcoming requirements notice says the game will operate exclusively with DirectX 12 under those requirements. The manual is historical guidance, not a substitute for the newer requirements notice or your storefront’s current installation flow.

How to verify The Witcher 3 game files

If the game will not launch or you suspect damaged files, verify or repair the installation in the storefront where you own it. CD PROJEKT RED documents these client paths:

  • GOG Galaxy: Customize → Manage installation → Verify/Repair.
  • Steam: Properties → Installed Files → Verify integrity.
  • Epic Games Launcher: Three dots beside the game → Manage → Verify.
  • Battle.net: Select the cog icon → Scan and Repair.

If verification does not resolve the issue, check whether your PC meets the requirements for the build you are using and whether your graphics drivers are current. CD PROJEKT RED’s launch-support guidance includes additional troubleshooting, but verification is the appropriate first storefront repair step.

How to back up saves before a clean reinstall

A clean reinstall is a troubleshooting measure, not a routine setup step. Back up your saves before removing local files. CD PROJEKT RED identifies the save folder as %userprofile%DocumentsThe Witcher 3gamesaves.

  1. Copy the contents of the save folder to a safe location outside the game’s folders.
  2. Disable cloud saves in your storefront client for the duration of the procedure.
  3. Uninstall the game using the owning storefront.
  4. Remove the client’s game folder and the local Witcher 3 Documents folder.
  5. Restart the PC, then reinstall the game without mods.
  6. Restore the backed-up saves to the save folder. Re-enable cloud saves afterward if you use them.

If Windows permissions cause installation problems, CD PROJEKT RED gives installing at the drive root as an example workaround. Check that the chosen drive has sufficient space and is suitable for the installation.

What to know about Remastered and existing saves

CD PROJEKT RED says existing saves are compatible with Remastered, but character skills reset; existing achievements carry over. Availability of earlier versions depends on storefront, so check the platform-specific options above before changing builds.
