This probably means that Tcl wasn't installed properly.

PythonScript/PythonLib/tcl/tcl8.6/init.tcl

Line 19 in fce7c26

package require -exact Tcl 8.6.13

PythonScript/PythonLib/tcl/tk8.6/tk.tcl

Line 14 in fce7c26

package require -exact Tk 8.6.13

Changing both require version strings to 8.6.15 avoids error.

Inside _tkinter binary is a string:

D:\a\1\s\externals\tcltk-8.6.15.2\amd64\lib\tcl8.6

Same string in PS v3.0.20.0 _tkinter binary.

PS v3.0.19.0 _tkinter binary has a different string:

D:\a\1\s\externals\tcltk-8.6.13.0\amd64\lib\tcl8.6

Appears that PS v3.0.19.0 is the last v3 version which matches the Tk/Tcl requirement of exactly 8.6.13 .

Downloaded tk8.6.15 source from SourceForge and compared tk.tcl with v3.0.21.0
