I use the Windows Linux Subsystem to run external scripts during a Sequencer test run. So I use the Sequencer Run External Process to launch WSL.exe and run a tcl script from there.
This is the command line, <wsl tclsh /mnt/z/test/Scripts/create-results-directory.tcl>.
When I try it with 5.26 or 5.31, I just get a Fail on that step in the sequencer..
This works fine in STC 4.95....
I tried specifying the full path to wsl.exe in windows/system32, but that does not help.
