# 1. Kit and installation
Lay the kit on a table. The current eight-Tracker set includes eight Trackers, the Excap Link 2.4G Dongle, a camera and its mount/cable, a charger and charging cable, stickers, and the new straps: two long, two medium, and four short. Your shipped Trackers use the v2 shell that fits these straps.

If you already play VRChat through SteamVR on this PC, go to the next section. Otherwise, install [Steam](https://store.steampowered.com/about/), then install [SteamVR](https://store.steampowered.com/app/250820/SteamVR/) and [VRChat](https://store.steampowered.com/app/438100/VRChat/) from Steam. Connect and wake your headset, start SteamVR, and wait until SteamVR shows the headset as tracked. **Do not continue with SteamVR output while the headset still says Not Ready or Disconnected:** SteamVR can be open without a live headset, and Excap cannot send the full-body tracking data into that SteamVR session until the headset is connected and tracked. Then leave VRChat closed while you install Excap.
## Install Excap Studio
1. Open the [official Excap Studio downloads page](https://www.elecholic.tech/resource/downloads/). Choose the **Windows Installer**.
2. Run the installer. On **Installation options**, leave **2.4G Dongle driver** and **Excap SteamVR driver** selected, then click **Install**. The installer may request administrator access and close Steam/SteamVR to install its driver.
3. Open **Excap Studio** after installation.
You do not need to download and run a second driver installer for first setup. The downloads website may show an older separate driver link; use the **2.4G Dongle driver** included in Excap Studio for this route.
**If Excap SteamVR driver says “SteamVR not detected” and its box cannot be selected:** finish installing SteamVR first. Then open **Setting → About → SteamVR Driver** in Excap Studio and use its **Install** action. This is a recovery step for installation order, not a separate download.

1. Plug the supplied **Excap Link 2.4G Dongle** into the PC.
2. Open **Device** in Excap Studio. Check the 2.4G Dongle status icon.
3. Turn on each Tracker with a short press of its button. Wait for eight Tracker cards to appear.
4. Pick up one Tracker and use **Blink** in its detail panel to match the card to the physical Tracker. Add its body-part sticker after you confirm its assignment in step 3.

The screenshot is an example with scripted Tracker data; check your own screen.
The yellow **Disconnected** text at the top of Excap Studio is the **data forwarding mode**. It can still say Disconnected at this step even when the Dongle and eight Tracker cards are online. You will select **SteamVR** there in step 4.
**If the Dongle is missing:** reconnect it and open **Setting → About → 2.4G Dongle Driver** to check the installed driver. **If fewer than eight Tracker cards appear:** charge and turn on the missing Tracker, then check the Dongle. Use [Wire Pair Trackers](https://wiki.elecholic.tech/books/excap-beginner-guide/page/pair-trackers) only if a Tracker is unpaired or on a different channel.
