hi all, I have learned a few things from this post, DarkShadows thanks for the effort. And i have one issue i cant figure out: 1) I Use Silent .Net Maker by Tomcat76 to make DNF11.exe and DNF20.exe packages 2) I followed your steps to the letter for creating DNF35.exe 3) for testing i installed winXP(sp2) on my laptop and executed dnf11.exe and dnf20.exe, so i installed both, and restarted my laptop 4) when the laptop booted i executed dnf35.exe, and this is where i got stuck, DNF35.exe wants to download things, i guess, and installation reported it cannot download blah, blah, blah........ I h8 when i get stuck almost at the very end of everything I tried again to make DNF35.exe, but this time i didn't delete dotNetFX20 folder, so i left it there,(only deleted 64bit) and now it works, but in add/remove it reports dotnetframework2.0SP1 and dotnetframeworkSP1, does it really matter? any advice or suggestion is more than welcome cheers
