Errors during installation and first-time startup

Solving certificate issues during startup

This troubleshoots the following issue:

During either installation or first-time startup of Grunt, an error message that suggests a problem with adding Grunt's certificate appears. Certificates are used by Windows to verify that the program you're installing is genuine.

If you are not the administrator of you computer, and/or certain other technical conditions are met, an error message will appear that looks something like this:

Workaround - install the certificate manually

Windows allows you to add certificates manually. To do so, begin by locating the Grunt installation file. It will be named something like "grunt-####.##-x64.msi", with the hashtags being the year and version of your installation file.

  1. Right click the installation file and click "Properties"
  2. Go to the "Digital Signatures" pane
  3. In the Signature list, there should be a single signer "Altua As".
  4. Click "Details". A new window will open.
  5. Click "View Certificate". Again a new window will open.
  6. Click the "Install Certificate" button. You should now see the "Certificate Import Wizard".
  7. The "Store Location" should be "Current User", which is normally selected by default.
  8. Click next and you will see a window with two options. Select "Place all certificates in the following store". "Click Browse" and scroll down till you find "Trusted Publishers". Select this and click OK.mceclip2.png
  9. Click Next and Finish.
  10. The Grunt certificate should now be added to your Trusted Publishers.

Next steps

  • If you saw the error message during installation, you can now retry the installation.

  • It may be necessary to restart your computer.
