troubleshooting .net framework 3.5 won't install on windows 8.1

when this .net 3.5 framework cannot install on my windows 8.1 it make other installation fail (sourcetree, visual studio 2017). it also make uninstallation fail (like visual studio 2015)

after following some forum, i follow this thread https://www.softwarecrew.com/2012/07/net-framework-setup-verification-tool-adds-net-4-5-windows-8-support/

i install the .net framework verification tool and verify that .net 4.0 is running, and there are some comments on forum to suggest removing .net 4.0. i hesistate

eventually on the same blog by Aaron Stebner on .net framework cleanup tool at https://blogs.msdn.microsoft.com/astebner/2008/08/28/net-framework-cleanup-tool-users-guide/
As mentioned by Aaron, this tool is the last resort. Good news is that within this blog there is this .net framework repair tool 

i download and run the repair tool till the step to restart the windows installer service for me. i then successfully install .net framework 3.5 (along with 2.0 and 3.0). the last step is of course restart the pc
