Hi RicaNeaga, I'm not really a silent installer specialist, it's just a hobby, but i will try to answer you: Beside SFX Maker that you already know, you will maybe like to try 7-Zip SFX Maker. i do know RegFromApp, in fact i have used it before discovering RegShot, it is also in my utilities AddOn that i share here: [AddOn] Utilitaires. I'm curious of the reasons you think it is better than RegShot, in my opinion RehShot is more powerful, as it can see the whole registry, not only one app, and it also can export in inf format, something that RegFromApp can't do. However I don't know Reg2exe, thanks to mentioning it, have to try it some day ! I rarely use SFX (or AddOn) makers, i have tested a few and they generate sub optimal config files in my opinion so I prefer to populate the config file myself, it's a good practice ! About registry entries, there is many ways to add them with a sfx: The most simple way i'm aware: regedit /s RegFile.reg Can be run directly from the sfx, or by a batch/cmd file called by the sfx There is also the possibility to add the registry entries directly from the cmd, or even directly from the sfx config file because RunProgram="hidcon:cmd /c Will run a hidden CMD shell, and as you can see in my config file, you can directly enter some command lines in the config file (But with some subtle differences in the syntax, so it may be more simple to do all the command in a .bat/cmd file run by the sfx) RunProgram="hidcon:cmd /c del /f /q \"%PUBLIC%\\Desktop\\Virtual CloneDrive.lnk\"" is equivalent to del /f /q "%PUBLIC%\Desktop\Virtual CloneDrive.lnk" in a batch file. (you can see the syntax is slightly different ) I think your config file parameters is wrong, if your installer (VLC in this case) is in the sfx archive, you can run it this way: RunProgram="vlc-2.0.4-win32.exe /L=1033 /S" No need to add variables, the sfx will run it from a temporary folder and it will be deleted after execution so no need for deletion command neither in this case. 7 ZIP SFX is very powerfull especially if you use the modified module. (syntax is explained and some examples on this site) I also often open the sfx made by others (with 7zip split) and i try to understand what each command will do, it's the best way to learn.
