You need to verify whether the VirtualOutlook key exists in the following location in the Windows registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\XX.0\Common\InstallRoot\Virtual\VirtualOutlook

or

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Office\XX.0\Common\InstallRoot\Virtual\VirtualOutlook

where XX.0 stands for the Office version, i.e. 15.0 and etc.

See Determine whether Outlook is a Click-to-Run application on a computer for more information.
