You have to monitor Nero installation (I used Total Uninstall) and compile a launcher to do the minimum registry entries to start nero.exe whith the minimum files. NeroExpressPortable.exe do the same thing that NeroPortable.exe but start nero.exe with /w switch. To compile launchers, I used NSIS but you can use AutoIt or a simple batch. The launcher try to backup registry entries and unreg dlls but to avoid error messages when leaving it don't unreg AdvrCntr3.dll so : Don't use if you have Nero 8 installed !
