### Description

## Description

I'm having an issue with DMS Greeter on Arch Linux with Niri.

When I try to start the DMS Greeter, it fails with this error:

```text
/bin/sh: line 1: /usr/share/quickshell/dms/Modules/Greeter/assets/dms-greeter: No such file or directory

### Expected Behavior

/usr/share/quickshell/dms/Modules/Greeter/assets/dms-greeter

### Steps to Reproduce

1. Install DankMaterialShell and DMS Greeter on Arch Linux.
2. Configure greetd to use DMS Greeter.
3. Reboot the system.
4. When greetd starts, DMS Greeter fails to launch.
5. The following error is displayed:

/bin/sh: line 1: /usr/share/quickshell/dms/Modules/Greeter/assets/dms-greeter: No such file or directory

### Error Messages/Logs

/bin/sh: line 1: /usr/share/quickshell/dms/Modules/Greeter/assets/dms-greeter: No such file or directory

### Screenshots/Recordings

Start by reproducing the DankInstaller and greetd setup on Arch Linux with Niri, then check whether /usr/share/quickshell/dms/Modules/Greeter/assets/dms-greeter exists after installation. Trace where DMS Greeter expects this path to be provided; done means greetd can start the greeter without the reported “No such file or directory” error.
