# get-vnc.ps1
|
|
# Downloads a portable VNC server (UltraVNC) for Windows and places its
|
|
# files into a local "vnc" folder so web-vnc can auto-launch it with --spawn.
|
|
#
|
|
# Usage (from repo root): .\scripts\get-vnc.ps1
|
|
# Override the download URL(s): .\scripts\get-vnc.ps1 -Url "https://.../UltraVNC_x64.zip"
|
|
#
|
|
# If all download attempts fail, the script opens https://uvnc.com/downloads.html
|
|
# in your browser — download the UltraVNC .zip (NOT the installer), extract it and
|
|
# copy winvnc.exe together with its companion .dll/.dsm files into the project's
|
|
# "vnc" folder, then run `run.bat`.
