During the install of Sisense, you may run into the following error: 
We're sorry, There was an error with your Sisense installation
Service 'W3SVC' (W3SVC) failed to start. Please restart your computer and try installing again.
The W3SVC service is a Windows service that is responsible for making IIS (Internet Information Services) work. The W3SVC service also manages the HTTP protocol and HTTP performance for IIS which needs to be running to allow Sisense (and other sites) to work.
This issue is indicating one of two things:
  1. IIS or some of the program's components are not installed on the machine and failed to install during the Sisense installation process. 
  2. One of the IIS services are not currently running (either IIS overall or W3SVC service).


To resolve this issue, please do the following:

Installing and Enabling IIS

  1. Close out of the Sisense Installation 
  2. On your machine, search "Turn Windows features on or off"

  3. Look for "Internet Information Services", and make sure that all of the components which are checked in this screenshot are checked on your machine:

    Internet Information Services > World Wide Web Services > Application Development Features 

  4. Restart your machine.
  5. Attempt the Sisense install again
  6. If this does not resolve your issue, please reference the Restarting IIS Services section of this article.

Restarting IIS Services

Restart IIS
  1. In your start menu type 'cmd'.
  2. Right click the shortcut and choose "Run as Administrator"
  3. In the command line, type: iisreset, hit Enter and wait for the IIS server to restart.
  4. If you end up getting some sort of error about not having IIS

Start the W3SVC Service
  1. In the command line, type net start w3svc, hit Enter and wait for the W3SVC service to start
    • If it is already started, the CMD line will tell you
  2. Close the command prompt window.
  3. Try to run the Sisense installer again as an Admin
