Respectfully......
Look at the thread... I was the one who answered the OP with the solution that worked. And, was thanked.
Yes the all caps and exclamations were too much. Mia culpa.
Now to your issue. ("Still haven't overcome this issue.")
It is the same problem - did you actually go to Control panel / programs and features / turn Windows features on and off / turn on .Net Framework 3.5 (includes .NET 2.0 and 3.0) / OK??
You don't "download" it - you turn the feature on via programs and features (and Windows downloads what it needs)
Or, Bob just answered someone - I think yesterday that was having an issue with Sentinal.
Maybe the same issue?
The answer is here - for you too ("Still haven't overcome this issue"............)
I had hope for a minute. BUT NOOOOOOOOOOO! lol
Followed these directions hoping it would be as easy as you said, but WIN10 has other ideas. checked off the .Net Framework 3.5, clicked ok. Said it had to DOWNLOAD SOMETHING. Clicked on this and sure as shootin it went into an infinite loop...infinitely thinking....spoooooooling.
Went to about 1/5th of the bar turning green to load and nothing. Just kept thinking. Also wouldn't cancel using the button or close using the "X:" in the corner. (Just fabulous!!!) Was working, working, working and said to not turn off the computer. But did nothing. Tried the switch and it wouldn't turn off! (The Audacity!) Finally just turned off the power bar . Nearly had a heart attack when it came back on and was still spooling saying not to turn off computer. Then...voila. The WIN10 picture appeared and about 2 min later the desktop appeared. (Thank God!!!) Needless to say I was not having many good thoughts during all of this.
The moral of this story might well be that unless you are sitting at the computer which you are explaining how to fix, it's probably wise to suggest and not be "**** sure" of the results. As far as I can determine, it still doesn't have the required .Net 2.0 to make Sentinal work.
I really hate Windows 10!!!!!!!!!!!!!!!!!!
