DISM error 87 the add-package option is unknown

Question

I am attempting to manually install Windows update KB2999226. I have extracted the msu file, but when attempting to install the .cab file through dism, I get the following error.

Solution 1

Check "Windows Modules Installer" Service (TrustedInstaller.exe) is not disabled. It solves my similar problem

Solution 2

DISM global options are NOT case sensitive.

DISM feature names ARE case sensitive.

I noticed you're doing this online. Is there a particular reason you're using DISM instead of WUSA?

wusa path\to\file.msu /quiet /norestart

Error 87 is indeed a parameter problem (verified by net helpmsg 87 and confirmed here) but I'm not seeing specifically what's wrong with the syntax.

Did you copy/paste from the web or manually type it? If the former, try the latter just to be sure it didn't use some strange em-dash type character.

I've never run into a case issue, except when dealing with FeatureNames, so this would be a first. So to appease those who obsess over case (they likely come from a *n?x background ^_^) you could try doing it exactly as Microsoft has it documented and surround it on double quotes just to be sure:

DISM.exe /Online /Add-Package /PackagePath:"C:\tmp\tmp\Windows8.1-kb2999226-x64.cab"

Also, just to save us a bit of headache: You sure that's the proper path?

I'm on Windows 10 so the package doesn't apply to me but after pulling the .CAB from the .MSU, the command works just fine:

Try WUSA with the .MSU - you're making more work for yourself.

Screenshot does not work. Which is the reason your encourage to upload images to our imgur instead.

Screenshot should be working now.

[Your syntax is incorrect it is Add-Package not add-package...])technet.microsoft.com/en-us/library/dd744559‌​%28v=ws.10%29.aspx). Determined this by doing a google search by the way.

@Ramhound Makes no difference. Cmd is not case sensitive.

[Ramhound]

Have you tried? Those applets in my experience are case sensitive. What version of Windows?

[Plof27]

Yes I have tried. I'm on Windows 8.1

[Ramhound]

Looking into it this has to do with your user profile.

Welcome to Super User! Could you improve your answer by explaining how/where to check if the service is disabled?

Burgi, how does it not? It just worked for me. DISM indeed shows this unrelated error when TrustedInstaller is disabled.

Run (win+r) services.msc and on my Windows 7 enabling "Windows Modules Installer" fixed this issue.

thx for very cool trick with: net helpmsg 87.

No Windows commands are case-sensitive, as Windows is a case-insensitive OS. Windows commands and parameters are often presented with the first letter of each word capitalized since it makes it easier for readers, similar to how the first character words within a hashtag is capitalized.

Dism in Windows ≥8 isn't the same as Dism in Windows ≤7 - have you verified if you can use Dism from Windows ≥8 in Windows 7 (I'm assuming you're not using Windows 7 since it's EoL)?
