Failure to install .net 3.5 on Windows 10 Error 800f0922

I am unable to install .net 3.5 on my new install of windows 10. Steam tries to install this for basically every game I try to download, but it always fails with the error code of 800F0922.

I have attempted a number of different things

• running the command:

DISM /Online /Enable-Feature /FeatureName:NetFx3 /Source:E:\sources\sxs /All /LimitAccess

where E: is a Win10 ISO (the same one I installed with)

• running an offline installer version of the update




• System Reserved is 33% full on 500mb partition





• Putting a reg key at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Servicing with the name LocalSourcePath and REG_SZ value of e:\sources\sxs




• Running the command

dism /online /add-package /packagepath:E:\sources\sxs\microsoft-windows-netfx3-ondemand-package.cab

• Running the command

DISM.EXE /Online /Add-Capability /CapabilityName:NetFx3~~~~

• I have no gpos set




• restarting the windows update service (wuauserv)




• installing from appwiz.cpl > enable windows feature > .net 3.5




• ran this string of commands:

net stop wuauserv

net stop cryptSvc
net stop bits
net stop msiserver
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old 
    #that failed as an admin cmd lacks permissions
ren C:\Windows\System32\catroot2 catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver


and then

DISM.exe /Online /Cleanup-image /Scanhealth
DISM.exe /Online /Cleanup-image /Restorehealth

Every different way of installing listed the exact same error 800f0922

I am stumped, guys.

Answer

I had a similar issue, evetually it was related to prior installation of .net 4.6 feature

These are the steps I used:

1. In the Programs and Features screen select from the left pane "Turn Windows features on or off"




2. At the beggining of the list there should be .Net Framework 3.5... and .Net Framework 4.6... nodes




3. The 4.6 option might be selected or partially selected, so verify what the selections are, remove them and click OK - they should be removed




4. Execute the DISM command from above which should succeed




5. Return to the features screen and apply back the options you removed

Hope it helps
