Hello António,

please try to install the Outlook plugin by saving the installer file locally on your hard drive, right-clicking on it and choosing "Run as Administrator".

If this won't help, please make sure that the following software is installed on your computer:
- Microsoft .NET Framework 4 ( http://www.microsoft.com/downloads/en/details.aspx?familyid=9cfb2d51-5ff4-4491-b0e5-b386f32c0992 ) and
- Microsoft Visual Studio 2010 Tools (http://www.microsoft.com/downloads/en/details.aspx?FamilyID=06c32242-2289-4471-93aa-ce96aa5cbc36 )

Best regards,
