checking the Check Box in Main GUI (Check for needed tools and download if necessary) I got a HTTP-404 error in BSORConfig.script with 'hiderun.exe'. Seems to be a wrong link ('Tools' instead of 'Tools/LiveXP')
unchecking this line I got the next error in BSORCopy.script section [From_CD] with IniWrite+escapes (seems Peter has found)
Changing the line to
TXTAddLine,%target_win%\TXTSETUP.sif,SetupData,OsLoadOptions=#$q/fastdetect#$qI could continue to next error message
BSORCopy.script section [Copy-CodePage] - could not copy 'c_1252.nls'
TXTAddLine instead of TextAddLine
