[Error Code] GetOutlookExePath.*Failed [Relevant Links] System Requirements [Explanation] 
It appears that the machine running the GAMME migration tool doesn't have Outlook installed. A fully up-to-date supported version is required for all Exchange and PST file migrations as Outlook includes a library for translating email messages from Microsoft's proprietary format to the MIME standard prior to the upload to Google's mail system. To resolve this issue, please install a compatible version of Outlook as described in the administration guide for the GAMME tool on the machine running the tool, then attempt the migration again. If the machine running the GAMME tool already has a compatible version of Outlook installed, please try uninstalling and reinstalling Outlook, ensure that you're able to open Outlook, and ensure Outlook has the latest patches.
