Title says it all. I keep getting this error whenever I try to install .NET Framework 3.5 on Windows 10. I've tried both the Add Features and the sxs DISM command methods (I've also tried this in Safe Mode) but they still do not work. Could someone help me? Thanks in advance. Here's the DISM.log (replace the "(dot)" with "."): drive(dot)google(dot)com/file/d/0B9RIYKhXSa0GWFh0bGFkSmc5LW8/view?usp=sharing EDIT: Just solved it by downloading the cab package located in here: forums .mydigitallife. info/threads/57050-Windows-10-Hotfix-Repository?p=1106641&viewfull=1#post1106641 and running this in an elevated command prompt: Code: dism /online /add-package /packagepath:D:\sources\sxs\microsoft-windows-netfx3-ondemand-package_1c89e2ded9ddd050dde8e723c5806704416dd363.cab where the packagepath is location of the downloaded file. After that .NET Framework 3.5 is enabled.
