Recently I was working with one of my customer, where they installed Outlook 2013 (32-bit) on Windows Server 2008 R2 (64 bit) environment. Every time when you start Outlook 2013, it runs an installation (Microsoft Office 64-bit Components 2013) – just like the below. I know it’s strange.
They tried repairing/fresh install, updated latest fixes as well – still it haven’t fixed this behavior; strangely this happened only in this server. To fix the error, they tried the following: Added Windows Search Service to the File Services role on servers.
Adding related thread that I found the MSDN Community is here. Happy troubleshooting!!
