I've taken note of your key phrase: 'Witchfire instal the new version for windows'. I'll provide you with a summary of the text you provided.

Witchfire is a single-player first-person shooter that will launch into early access on September 20. The game does not include multiplayer or co-op modes at launch, focusing instead on delivering a challenging and immersive solo gaming experience.

The game requires an NVIDIA GeForce 537.42 WHQL driver for optimal performance in Witchfire, Cyberpunk 2077: Phantom Liberty, and Warhaven.

Regarding installation, I found that the game will be available on Steam/PC & console platforms. However, there is no information provided about installing the new version specifically on Windows.

If you're looking to download and install Witchfire on your Windows device, here's what you can do:

1. Go to the official Witchfire website or Steam store page.

2. Click the 'Download' button to redirect to a download page (Datanode, Qiwi, GoFile, PixelDrain).

3. Follow the instructions provided on the download page to complete the installation process.

Please note that as Witchfire is still in early access, it's possible that the installation process may change or additional steps may be required for optimal performance.

Let me know if you have any further questions or concerns!
