# Using NDI Source (Windows)

We’ve been receiving inquiries about NDI sources not showing after updating to PRISM Live Studio v4, so we’d like to provide the tips on using it in v4.

First, for the users who are using PRISM which is between v4.3.0 to v4.4.2, if you want to use NDI source. Three things are required. 

1. **DistroAV** (Formerly OBS-NDI) **plugin 6.0.0**
2. **NDI Runtime >=6**
3. **Remove old OBS-NDI plugin**

In PRISM Live Studio v4 version, the NDI function is provided in the form of a plug-in, so if the plug-in is not installed, the NDI source will not be exposed in the source list.

And please note that PRISM verisons which is between v4.3.0 to v4.4.2 are based on OBS 30.2, so you need to download the **DistroAV** plugin 6.0.0 which matches OBS 30.2.

​Please refer to the following for detailed instructions.

**Download the OBS NDI plugin and copy it to the PRISM Live Studio folder.**\

#### Remove old OBS-NDI plugin

* If you installed OBS-NDI via the `obs-ndi-*-installer.exe` installer:
  1. Use `Add/Remove Programs` and uninstall `OBS-NDI`
* If you installed OBS-NDI manually from the `obs-ndi-*-windows*.zip`:
  1. Delete files `%ProgramFiles%\obs-studio\obs-plugins\64bit\obs-ndi.*`
  2. Delete folder `%ProgramFiles%\obs-studio\data\obs-plugins\obs-ndi\`
  3. Delete files `%ProgramFiles%\PRISMLiveStudio\obs-plugins\64bit\obs-ndi.*`
  4. Delete folder `%ProgramFiles%\PRISMLiveStudio\data\obs-plugins\obs-ndi\`
