Describe the Bug

Description

The installer gets stuck indefinitely at the step "Adding Sunshine directories to PATH" when Sunshine is installed to a drive other than C: (e.g., F:\Programs\Sunshine). The update-path.bat script appears to hang without producing any output or error message.

Steps to Reproduce

1. Download Sunshine installer (e.g., sunshine-windows-installer.exe)
2. Run the installer
3. Change installation path to a non-C: drive (e.g., F:\Programs\Sunshine)
4. Proceed with installation
5. Observe that the installer hangs at "Adding Sunshine directories to PATH"

Expected Behavior

The installer should complete successfully regardless of the installation drive.

Actual Behavior

The installer hangs indefinitely at the PATH modification step. The update-path.bat script produces no visible output and does not complete.

Workaround

Installing to C:\Program Files\Sunshine works correctly. The issue only occurs with alternative drive letters.

Environment

• OS: Windows 10/11
• Sunshine version: [tu versión, ej: v2025.118.151840]
• Installation path: F:\Programs\Sunshine (or any non-C: drive)

Expected Behavior

The installer should complete successfully regardless of the installation drive.

Additional Context

Manually running update-path.bat as administrator also produces no output when Sunshine is installed on a non-C: drive. This suggests the script may have hardcoded paths or incorrect handling of drive letters.

1. We're no longer shipping the .exe
2. All the installation scripts have been re-written since the version you mentioned
3. We don't support old versions

Please try the .msi from the latest pre-release and let me know if the issue remains.

Hi @ReenigneArcher,

I tested with the latest pre-release Sunshine-Windows-AMD64-installer.msi (v2026.824.30334) and the issue still persists.

The MSI installer still hangs indefinitely at the "Adding Sunshine directories to PATH" step when installing to a non-C: drive (e.g., F:\Programs\Sunshine).

Steps to reproduce:

1. Download Sunshine-Windows-AMD64-installer.msi from latest pre-release (v2026.824.30334)
2. Run the installer
3. Change installation path to F:\Programs\Sunshine (or any non-C: drive)
4. Proceed with installation
5. Installer hangs at "Adding Sunshine directories to PATH"

Workaround still works: Installing to C:\Program Files\Sunshine completes successfully.

Thanks,
