Finally I have compiled my NeroLite 8.3.2.1 with the last SDK1.16.1.2. Thanks a lot Acheron for your work. I had problems with the sripts, though. In NeroLite_europe.cmd it gives me an error "can't find c:\Program" It's a problem with the lines start /B /WAIT "PreProcessing - NeroLite_europe_lite.iss" /low "%InnoSetupPath%\iscc.exe" "NeroLite_main.iss" /dLite > NUL start /B /WAIT "PreProcessing - NeroLite_europe_micro.iss" /low "%InnoSetupPath%\iscc.exe" "NeroLite_main.iss" /dMicro > NUL To compile it I had to change them with: start /B /WAIT "PreProcessing - NeroLite_europe_lite.iss" /low "C:\Program Files\Inno Setup\Inno Setup 5\iscc.exe" "NeroLite_main.iss" /dLite > NUL start /B /WAIT "PreProcessing - NeroLite_europe_micro.iss" /low "C:\Program Files\Inno Setup\Inno Setup 5\iscc.exe" "NeroLite_main.iss" /dMicro > NUL It seems the %InnoSetupPath% only takes "C:\Program". Do you know how to fix this? My o.s. is Windows Vista SP1 Spanish. And thanks a lot darks0ul for the Recode SDK. Finally I can use Recode in my NeroLite. I also have some problems with the compilaton of the pack spanish version. It seems NeroRecode_eng.chm, NeroRecode_esp.chm and others files were not in the right folder. Anyway, I have copied them manually and now it works.
