for those who want to build a silent .Net 4 with updates includes, you should look for "SoLoR" .Net installer (contains both x86 and x64 / ~100Mb) => [up-to-date] then read the very interesting forum "mydigitallife" to understand how to build a slim & silent .Net4 installer => from page 135 to 138 i used ricktendo64 MST slimmers too (p. 136), and everything works fine :-) i could build my own .Net Framework4 up-to-date. it contains both x86 & x64 and only x86 is installed on x86 machine :-) i added 3 updates for a 47Mb result installer.
