As stated in the title, the 3.5 framework is not working properally. whenever I try to run application that require it, I get an error similar to this,

I checked my system folder, and none of these folders exist, nor do the DLLS. Is there any reason for this? I used the Framework uninstall tool and uninstalled all the previous versions. and reinstalled the latest one and the service pack afterwards.
