I am using this version of TCL on Windows 10 64-bit. Seems to work just fine and requires no installation -- just copy and go. ``` 2019-04-22 15:26 24,341,745 tcltk86-8.6.9-0.tcl86.Win10.x86_64.tgz ``` <https://bitbucket.org/tombert/tcltk/downloads/> about 8th from the bottom. Works just fine since only very rudimentary TCL is required. Untgz wherever you please and put the bin directory in the path. This version of Tclsh works, is tiny, has no dependancies, and is compiled with a real compiler, and does not require you to register anything. The major plus is that it works the way God intended when she invented computers -- there is no need to run an opaque installer executable -- just copy and go, like in the beginning times before the invasion of the eternal Septemberites with their need for wet-nurses and nannies.
