Add PI DataLink certificate to store of trusted certificates

If you configure Microsoft Excel to require add-ins to be signed by a trusted publisher and you install PI DataLink outside of the standard C:\Program Files directory, then you must manually add the PI DataLink certificate to the store of trusted certificates.

1. Open a command window as administrator.

2. From a command prompt, navigate to the directory that contains the PI DataLink certificate (pidlcert.cer).

   You can find the certificate in the Excel subfolder of the installation folder (defined by the PIHOME environment variable).

3. Enter the following command:

   C:\Windows\System32\certutil.exe -addstore TrustedPublisher pidlcert.cer
