@ mgadallah Both files are here: $OEM$\CDLMROEX\ImgBurn\ImgBurn.exe (downloaded EXE renamed) $OEM$\CDLMROEX\ImgBurn\ImgBurn.js You don't have to use this JS file unless you get those messages. Otherwise, just use /S. I managed to uninstall then re-install ImgBurn in the hope of capturing the two messages. Unfortunately, I got the first message only. (now, eh!) If I remember correctly, the second message is about "Do you want to keep your current settings? Yes/No". Well, BTW, I use these tweaks in my CleanUp.cmd: @ Takeshi I have CDIMAGE and CDBURN already in my System32 (via $OEM$). I think this is why ImgBurn thinks it's already installed! I'm just guessing. Ah, then I was just lucky with nLite! Thank you for the info about unicode names. I should take care of this. @ bledd Thank you for the tip. (haven't read it before posting!) Have you just renamed "C:\Program Files\ImgBurn\ImgBurn.exe" to img.exe and moved it to System32? If so, don't I need any more files from installation?
