You may see the error below when attempting to use the Outlook functionality in SI5 even when running Office 2010 on your machine.
Microsoft Office Outlook 2007 has not been installed.
Cause:
This occurs on Win7/Vista machines where either:
SI5 is running as Administrator and Outlook is running as a normal user
Outlook is running as Administrator and SI5 is running as a normal user
Solution:
Run both SI5 and Outlook as Administrator, or run them both as a normal user. To do this, right-click the program you wish to open and choose "Run as Administrator". Another simple work around is to close Outlook while SI5 is open and the re-launch Outlook, it will re-open with the same permission level as SI5 and this error will not occur.
