Have following small ruby file main.rb as input to tebako

fw = File.open("tebako1.txt", "w")
5.times{ fw.write("a line of data/n") }
fw.close

var = ' --> appended'
puts "Enter a word on console"
line = gets.chomp
puts line + var
fw = File.open("tebako2.txt", "w")
5.times{ fw.write("End of program/n") }
fw.close

Used following input to run

ridk enable ucrt64
tebako press --entry-point main.rb  --root C:\TEBAKO\source --Ruby 3.2.7 --output C:\TEBAKO\exe_out\runme

An executable is produced (first 2 char are MK)

This is the console log:

Created tebako package at "C:/TEBAKO/exe_out/runme.exe"

When executable is run from tebako/exe_out following error

C:\TEBAKO\exe_out>runme.exe
runme.exe: No such file or directory -- A:/__tebako_memfs__/local/main.rb (LoadError)

If run from explorer screen flashes once and terminates

There is no console activity and no files are created

This appears to work (code generated is correct)

C:\TEBAKO\exe_out>runme --tebako-extract
Extracting tebako image to 'source_filesystem'
'tebako-runtime' was not loaded.

Have tried multiple examples without success - sure I am missing something simple

Tried adapting several on line examples without success but may be missing what trebako runtime is

I have RESOLVED the problem will update with complete instructions after I have fixed issues still bothering me
