I tried to install windows essentials 2012 on my windows 10 pc. In the past I have downloaded this with out issues. then my pc had problems (not regarding windows essentials). I had the same version of windows 10 (but not my copy) installed and everything seemed fine, until I came across this. when I try to install windows essentials, it fails and pops up with this error message (I have not shortened this in anyway):

"An app on your pc needs the following windows feature:

.NET Framework 3.5 (includes .NET 2.0 and 3.0)"

I click on the option "install this feature"

it searches for the required files and then says it couldn't be installed

"the following feature couldn't be installed:

.NET Framework 3.5 (includes .NET 2.0 and 3.0)

the referenced assembly could not be found.

error code: 0x80073701"

I decide to search for this error and find a forum that says this will mainly happen if .NETFramework 3.0 has been turned off in the windows features. it says to open"turn windows features on or off", turn on the .NETFramework 3.0, and then it should be fine. 

I do that then it searches for the required files and then fails and says:

"windows could not complete the requested changes

the referenced assembly could not be found.

error code: 0x80073701"

the same error code as before, its just going round in circles. 

please help
