I'm having a problem enabling DotNet 3.5 on my win 10 pro, version 1809.

Whenever i try to enable 3.5 from the windows features menu, it open a windows "searching for required files" forever, without actually advancing.
sometimes the message actually changes to "downloading required files" but then that one hangs forever.

I tried every single solution i could find, from downloading the dotnet 3.5 SP1 package from the microsoft website (it asks me to enable 3.5 to install this software, and then gets stuck on searching for required files), to using the DISM method (stuck on Enabling Feature (s) forever)

I get no error codes or messages, it just basically just gets stuck whenever i try to enable or install dotnet 3.5.

Any ideas?

Are you able to open either Reliability History or Event Viewer?

There may be some specific error code(s) or warnings being logged when attempts to enable DotNet. 3.5 fail.

Key is to identify the reason for the failures and then seek the appropriate fix.

Read the following link for informational purposes:

https://windowsreport.com/net-framework-3-5-missing-windows-10/

The immediate objective is to discover what has gone astray and then focus on the applicable repairs.

Hey Ralston18, thanks for replying.

I checked event viewer, and it doesnt log anything while the "searching for required files" is running.
Keep in mind that it doesnt actually hang, it just keeps running endlessly, without actually advancing with the installation. I've left it running overnight, still searching for required files, or downloading required files but not actually advancing.

When i terminate the app through the task manager, it gives me this log through event viewer:

try this, make that batch file and try it using your install media

if none of what you tried and this doesn't work, it's clean install time for you.

Tried that too, doesn't help..

I think I can solve this somehow, the main issue is with the windows update service, if I download updates directly from the Microsoft website, it downloads and installs without problems. I don't think this warrants a clean install

I basically tried everything on the internet i could find, including every solution on the list in that link you've send me...

the DISM method just stalls forever. It gives me a message of Enabling features, but just remains like that indefinitely.

Trying to install the offline 3.5 package results in windows requesting 3.5 to continue with the installation of 3.5 framework, so pretty redundant.

Trying to enable 3.5 in the features menu returns a request to download 3.5. when i continue, it searches for required files, and downloads required files for 2 hours, and returns this error code: error code 0x80244018

I ran a sfc command and it returned a log file, did you take a peek in that?
