Product: Pavillion 15
Operating System: Microsoft Windows 10 (64-bit)

Good Evening,

 

I have n HP Pavillion 15-cs3075wm and I need to install Micorosft .NET Framework 3.5 in order to install a needed application for work.

 

When I try to download and install the application, it fails with an exception code

 

Rebooting the laptop does not resolve the issue.

 

Does anyone have any ideas or suggestions?

Hi:

 

Not sure how you are trying to do this, but the only way to install .Net Framework 3.5 in W10, is to go to the Windows control panel>programs>Turn Windows features on or off.

 

A window will open and a list will populate.  The first item that should show up is .Net Framework 3.5.

 

Check the box to install it and wait for the installation to complete.  It usually takes a couple-three minutes.

Hey Paul,

 

Thanks....the first time I tried that...I got an Exception error and it didn't work. I am trying it again. It looks like I might have missed the check boxes in the drop down in Control Panel to turn it on.

 

I'll let you know how it goes.

Windows Error Code 0x800F0950 - Which is not in the Microsoft Knowledge base Article, btw.

 

Reboots don't help.

Sorry that didn't work for you.

 

I've always been able to install it that way.

Hi Paul..

 

I was finally able to do it after I reset my Pavilion 15 back to factory settings and reinstalled all my applications and programs.
