Hi. There are some addons I have added to installation which are not present in installation when I tried it. These addons are .7z or .rar and have .cab inside beside .inf and .ini. These addons are mainly system files such as themes rycks pack etc. Can someone tell me what to do, because I think these addons should be sleapstreamed by nlite right after the process starts but they are not. Thx in advance M
