# JaxCore FAQs

## Performance

### Does JaxCore load on startup?

It does that by default. However, only modules and widgets are loaded, and the config hub will not load on startup. 

### Does JaxCore run in the background?

No. The configuration hub will not run in the background. Only activated modules and widgets will.

### Can I turn JaxCore off when I play games?

Yes. You can toggle on Gamemode in the JaxCore settings.

## Legacy issues

### JaxCore hidden / not showing / showing only in taskbar / JaxCore settings won't open

1. Go to the Rainmeter Manage panel (found in your app tray) 
2. Set `#JaxCore\Main\Home.ini` coordinates to `0 0`. If the option is greyed out, load it.
3. Unload and load it
4. After that, Re-create JaxCore's shortcut in it's setting page so that this issue never happens again

## Installation

Download JaxCore from [our website](https://jax-core.github.io)

### Installing in another location

Select option **3** when the powershell prompt asks for an installation preferences. Then choose a folder once prompted. It is recommended to choose an empty folder as the installer creates 2 folders in the selected directory. If the installer is stuck after clicking **OK**, press enter.

### Already have Rainmeter installed, but portably?

Run the following command in Powershell, replacing `<LOC>` with the absolute path to the folder you want JaxCore installed in, and this folder should contain the Rainmeter folder that you have installed to before.

```
<LOC>
├── Rainmeter       
│   ├── Rainmeter.exe
│   ├── ... other stuff
```

```
$o_Location='<LOC>';iwr -useb "https://raw.githubusercontent.com/Jax-Core/JaxCore/master/CoreInstaller.ps1" | iex
```

## In-app installer

### Unable to install anything within Core / Nothing happens when clicking green download button

#### Goofy-ah anti-viruses

This happens because your anti-virus prevented the Powershell instance to launch. To fix this, exclude the following paths in your anti-virus.&#x20;

```
## Standard installations:
%ProgramFiles%\Rainmeter
%AppData%\Rainmeter
%AppData%\JaxCore

## Rainmeter installations:
%ProgramFiles%\Rainmeter
%AppData%\Rainmeter
Documents\Rainmeter

## Custom location installations:
Exclude the folder that JaxCore is installed in.
```

Save your configuration in your anti-virus and restart.

{% endhint %}

#### Still unable to install anything?

Run the following command to install a specific module. Replace **YourFlyouts** with the name of the module that you want to install.

```
$o_InstallModule='YourFlyouts';$o_FromCore=$true;iwr -useb "https://raw.githubusercontent.com/Jax-Core/JaxCore/master/CoreInstaller.ps1" | iex
```

### After installer finishes, module still isn't installed

Try turning on **Use legacy .rmskin extension installer** in JaxCore settings.&#x20;

{% hint style="info" %}

## Reinstallation

Reinstallating would help remove broken folder structures and start fresh

1. Uninstall Rainmeter via Windows Settings
2. Delete `%appdata%\JaxCore` and `%appdata%\Rainmeter`
3. Install from <https://jaxcore.app>

{% hint style="danger" %}
Note: This will remove all modules & widgets.
