• Tcl/Tk 8.6.7 (x64) → OpenPGP Signature

• OpenPGP Release Signing Key

• IronTcl Package Client (beta)

Please note that the string "<base>" in the steps below represents the base directory where the ZIP archive gets extracted.

1. Extract the downloaded ZIP archive to the base directory where Tcl/Tk should be installed, while preserving path information.
2. Optionally, add the directory "<base>\Tcl\bin" to the PATH environment variable.
3. Optionally, create a copy of the file "<base>\Tcl\bin\tclsh86t.exe" named "<base>\Tcl\bin\tclsh.exe" (i.e. in the same directory) to ease integration with other software packages.

For security purposes, all executable and dynamic-link library files available for download have been digitally signed by "Mistachkin Systems". Please verify that all digital signatures are intact after downloading.

As an additional security measure, all files available for download have a corresponding OpenPGP signature file, with the official release signing key hosted on an entirely different network.
