RSAT tools not installing on windows 11. Error code = 0x800f0955

Question

For some reason some of my Active directory rsat tools have uninstalled. When i try to install it again via the " optional Features" page i get a " couldn't install " error. When i try to install via powershell i get an " Add-WindowsCapability failed. Error code = 0x800f0955" error.

i even tried installing other RSAT tools I don't need to see they would install and they did. for some reason it just wont install certain ones.

Things I've tried but did not work:

• installed via powershell
• installed via optional features
• Changed local group policy to allow optional features

Answer 1

i was able to solve the issue. i just redownloaded the RSAT tools from microsoft. Technically i shouldn't need to do this but it worked and now my active directory snapins are present.

Answer 2

Hi,

Can you try the fix ("Method 1") for 0x800f0954 to see if that helps?

Answer 3

I looked at both methods and i cant apply the solution in "Method 1" as i dont have that regedit structure they provided. i also could not apply the other solution you provided.

Answer 4

Try downloading the Optional Features ISO for Windows 11 from this link.

You can then mount the ISO and install RSAT using DISM or PS, mentioning the source path -- e.g., H:\LanguagesAndOptionalFeatures.

Alternate method:
