Nicelabel Proxy Service 2017 Is Not Running Instant

| Cause Category | Specific Reason | |----------------|-----------------| | | The proxy service encountered an unhandled exception (e.g., corrupt label file, invalid printer driver). | | Windows Update | A .NET Framework or Windows Security update changed permissions or broke dependencies. | | Dependency Failure | The service depends on other Windows services (e.g., Print Spooler, Remote Procedure Call). If those are off, the proxy fails. | | License Expiration | The network license file ( .lic ) expired or was moved. The proxy stops to prevent unlicensed printing. | | Port Conflict | The proxy listens on TCP port 5100 (default). Another application took that port. | | Corrupt Configuration | ProxyService.exe.config was manually edited or corrupted by a crash. |

If you are also using NiceLabel Automation and it won't start alongside the proxy, there may be a registry conflict. NiceLabel Help Center Registry Editor Navigate to: nicelabel proxy service 2017 is not running
