Installation ​

TLS 1.2 activation ​

For security reasons, Seald only allows the Outlook plugin to be downloaded through an encrypted connection using TLS 1.2. Windows 7 uses an older version of TLS by default and this can cause errors.

To fix this and activate TLS 1.2, please follow Microsoft's instructions.

Installation of the pre-requisites ​

To install the pre-requisites, you need to download the Microsoft VSTO tools and Microsoft .NET framework. Once downloaded, you can either install them with the graphical interface and follow the instructions, or programmatically by executing the following commands:

# Adding the Seald signature certificate
certutil -addstore TRUSTEDPUBLISHER "plugin-cert.cer"

# Quiet installation of plugin utilities
.\vstor_redist.exe Setup /q /norestart
.\NDP472-KB4054530-x86-x64-AllOS-ENU.exe Setup /q /norestart
