OK. I have verified and the result is: My .Net framework 3.5 distributable package size is (197 MB). Extract it again and delete the items you mentioned only in the list (i'm sure) Repackage the .Net framework 1.1 & 2.0 again according to Tomcat76's Silent .NET Maker guide. my resulting file sizes: (dotnetfx.exe + NDP1.1sp1-KB867460-X86.exe + NDP1.1sp1-KB928366-X86.exe) = 11,716 KB (dotnetfx2.exe + NDP20-KB928365-X86.exe) = 39,963 KB DNF35.exe = 66,400 KB I tried to reinstall them all But the .Net framewoke 3.5 have the same problem. any suggestion please
