# Error When Turning On the Remote Service

I'm getting an Unhandled Promise Reaction popup (Error: spawn UNKNOWN) when I try to set remote to ON. What should I do?

* If this pop-up appeared while installing or updating the launcher, please refer to the \[[Installation fails and repeats after the 'Required update' notice](/faq-en/launcher-download/7.md)] article.
* This occurs when the Netmarble Launcher is closed before the Remote setting is turned ON, or when the program was installed abnormally.
* The remote file is corrupted, so please access the file's installation path, delete the file, and reset it.
* For a detailed explanation, please check the solution below.

#### \[Solution]

1. Access the 'agent' folder in the path where Netmarble Launcher is installed.
   * Default installation path: C:\Program Files\Netmarble\Netmarble Launcher\agent
2. Delete all folders in the 'agent' folder. 
3. Reconnect to Netmarble Launcher > Retry "Remote Setting ON."
