Similar to #6 - tcl seems to be missing from the default installation on windows?
Works ok with full "default" install of python 2.7.x (with tk included) - so either a stripped down installer is being used vs the vanilla python distribution, or the tk dependency is being deselected by the automatic installation.
Quite annoying to track down as the application just starts and immediately crashes to desktop without alerting the user. Needed to be manually started from the command line through "python" to give any helpful output.
Working otherwise 👍
