OK this is what you have to do exactly from the readme.txt you have to enter this exact line

MKISOFS.EXE -C 0,11700 -V TXR2_ECH -l -o C:\TXR2\DATA.ISO C:\TXR2\DATA

(the above after TXR2_ECH is the letter small L and that is the letter small O)

make sure that you are entering it correctly and that the paths are generated (directories) like ECHELONs file says.
