I can't find an ISO with this name. Download it from Technet/MSDN subscription again. The error 14028 means file hash mismatch:

  ERROR_SXS_FILE_HASH_MISMATCH                                   winerror.h
# A component's file does not match the verification
# information present in the component manifest.
# 3 matches found for "14028"

so it looks like the ISO is damaged.

I'm getting this 14028 error. It won't download from Windows update. It won't work in dism. Can't do it in WSUS. What's the plan now?

I'm also getting HRESULT=800736CC in dism.log.

My ISO is en_windows_8_enterprise_x64_dvd_917522.iso

I have no idea what the hash should be but I can tell you the SHA1 for my download is 8da7ef239333b8f8959178faa61dbbc10c9ce550

Can anyone verify that re-downloading the ISO will actually fix this? It seems to be suggested in various places but nobody has actually said "yes this works".

Microsoft - sort it out.

Hi,

I am getting the same error message but with number 800736CC

"A component's file does not match the verification information present in the component manifest"

I upgraded from Win 8 to Win 8.1 and windows live mail failed to work asking for .Net 3.5.

Tried DISM, Control panel all return the same error. Also tried the .net Framework repair tool from Microsoft, no result, I am gettign the exact same error. It seems that somehow tghe installer is trying to use Win 8 files that do not match the required signature, instead of windows 8.1 or something like that.

Microsoft, please come with a solution, it is very frustrating!

Thank you,

Adrian

Hi,

check in your installed updates on the server whether KB2769166 is installed. This update changes the signatures of the .NetFrameWork assemblies and therefore you cannot use the files in the Windows Server 2012 install disk SXS folder.

Simply uninstall this update (KB2769166) and rerun the add NetFX3 feature command again, or use the GUI.

You should now be able to install the feature.

Hi,

thank you for your message, I tried to enable net3.5 and it worked now, did not need to uninstall anything.

Thank you

Same problem with 8.1. I have installation media which I can use as installation source no problem, adding .NET Framework with dism online is not possible. I cant believe such simple procedure is done so hard! .Net Framework 3.5 is required for many applications to run.

In dism.log I get 0x800f081 - source files could not be found.

HI everyone!

if you people are facing the error code 14028 while installing netframe 3.5 in windows 8 and 8.1 then all you have to do is install 7-zip then extract the folder sources\sxs from the ISO file into a new created folder(eg:net35) in C drive. Then run cmd as administrator and type dism.exe /online /enable-feature /featurename:NetFX3 /all /Source:C:\net35\sxs\ /LimitAccess . Everything went well for me to treat Error: 14028, now try ur luck.

My problem was solved By excluding Language Pack from the image. So "source files could not be found" was occuring because I first installed LP and then tried to integrate Framework. When I changed the process order in task sequence, everything worked.

Installing a Windows language pack before installing the .NET Framework 3.5 will cause the .NET Framework 3.5 installation to fail. Install the .NET Framework 3.5 before installing any Windows language packs.

This worked for me, when nothing else did. It drove me mad, I was just a step away from ditching 8.1 and coming back to 7. Microsoft - SHAPE UP!

The point is, that do not alter your installed OS before installing .net 3.5. Install it right after installing OS itself. Also running MS updates might cause this.
