Download ButConnect

The ButConnect remote access and support software tool is available free of charge. You always get the unrestricted version.

An installation is not required — after unpacking the downloaded package, ButConnect is ready for use.

When a new version is available, it's not necessary to download the full ButConnect package again and replace the files manually. Instead, you can use its (auto) update feature.

For an overview of new features, please take a look at the version history.

Packages

ButConnect is a portable and cross-platform software.

However, depending on your platform there are two different packages available: a full package (“bc”) with ButConnect and UltraVNC server & viewer for Windows and a minimal package with ButConnect only (“bcmin”) for all other systems.

Full Package (including UltraVNC server and viewer, for Windows):

• Download bc.zip (2021.10.29.7)
  (Unzip and then run ButConnect.exe)
• or ...
• Download bc.exe (2021.10.29.7)
  (Execute and then run ButConnect.exe)
•  
• If the message [ Windows protected your PC ] appears on your screen, you should request [ More info ] and then choose [ Run anyway ] if you want to ... connect anyway.
•  
• (The UltraVNC server and viewer are licensed under the GPL. In ‘GNU GPL’ terms, our “Full Package” is an aggregate.)

Minimal Package (for Linux, macOS, BSD, Solaris, Raspberry Pi and Others):

• In case your antivirus tool complains about the downloads, that's probably because we deliver VNC executables together with ButConnect. If you're unsure, try to download the minimal version of ButConnect that does not contain any other executables but still provides the full functionality to connect.
  Since those additional executables are for Windows only, this is also the proper version for use with Linux, macOS, BSD, Solaris, Raspberry Pi and others (again, as long as Mono is installed).
  It's then up to you to ensure that a VNC server and viewer or other tools to utilize the connection are in place.
•  
• Download bcmin.zip (2021.10.29.7)
  (Extract and then run ButConnect.exe — respectively mono ButConnect.exe)
• or ...
• Download bcmin.tgz (2021.10.29.7)
  (Untar/ungzip and then run mono ButConnect.exe)

Requirements

On Windows the .NET Framework 4.0 or newer needs to be present. This is already the case in Windows 7 SP1 or newer. On other systems Mono 2.11 or newer is required.
