Hi , i'm trying to install 7zip with a windows seven x86 pro , and I try to do it with Setupcomplete.cmd , so in the setupcomplete , I put this : FOR %i IN (C D E F G H I J K L N M O P Q R S T U V W X Y Z) DO IF EXIST %i:\AppsRoot.txt SETX AppsRoot %i: -mstart /wait %AppsRoot%\install\install.bat (it is in sources\setup\scripts) Then I do my install.bat : msiexec.exe /i %AppsRoot%\install\7z920.msi ALLUSERS=1 /qb! /norestart and I put it in %appRoot%\install. And it doesn't works , can sb tell me what to try ? Thanks
