Why do I get Error Failed to add local user: "MATLABWebAppsGuest" while registering WebApp Service?

3 views (last 30 days)
I have installed Web App Server and while registering Web App Service, I am getting this error-
ERROR: The service command did not execute successfully with the following error: [Error] The account already exists.
[Error] Failed to add local user: "MATLABWebAppsGuest".
[Error] Failed to install the web app server.
There no option to unregister, only register option is available.
Also, start button is disabled, so I cannot start my webApps.
How can I fix this?

This error is thrown when there is a problem with registered user.
You are trying to register the same user who is already registered.
But there is some problem with already registered user.
A simple workaround would be to delete the existing user from "Users and Groups".
To do this in Windows- 
​1. Press the Win+R keys to open Run, type lusrmgr.msc into Run, and click/tap on OK to open Local Users and Groups.
2. Click/tap on Users in the left pane of Local Users and Groups. 
3. Delete the existing MATLABWebAppsGuest user.
Once user is removed, restart Web App Server.
