Installation issues workaround - Office 365/Outlook 2016
As a heads up to anyone that is interested: The NetSuite for Outlook installer has some built in validation that is checking for specific versions of Outlook (Directly from the installation log: "Condition '(OutlookVersion="Outlook.Application.12" OR OutlookVersion="Outlook.Application.14" OR OutlookVersion="Outlook.Application.15")' evaluates to false."). Outlook 2016's version is "...Application.16".
As such, the installation finishes immediately, does not provide a screen pop warning, and does not install all of the required software (i.e. No Outlook COM add-in or Celigo folder created under Users/.../AppData/Local). So that is why the software appears to install but doesn't work, doesn't have you close Outlook 2016 if you had it open during the installation, and doesn't load the configuration/setup screen when finished. (For those users experiencing installation issues with Windows 10, there could be validation checking hardcoded in the installer as well.)
