I am having an issue finding this after installation. Here is my scenario.
I bought a 3 license code version of Office Professional Plus 2010 a little over a year ago. I have only installed on 2 machines thus allowing me one additional installation.
I just bought a brand new Lenovo desktop computer with windows 8. I immediately upgraded to Windows 8.1. The desktop came with the typical pre-installed programs one of those being a trial version of Microsoft Office.
I didn't do anything with the trial version, and installed my copy of Office Professional Plus 2010 and everything seemed to install okay. However, when I try to find it I can't find a folder with any installation files, but it's installed when checking in the control panel.
I can find Office Folders under c:Program files, but they say Office14.
By default, the folder location should be C:\Program Files\Microsoft Office\Office14 or C:\Program Files (x86)\Microsoft Office\Office14 (For 64-bit Windows but 32-bit Office installations).
Office15 would be Office 2013.
Assuming the trial version is Microsoft Office 2013 Professional Plus, the folder location would be located under C:\Program Files\Microsoft Office 15\root\vfs\ProgramFilesCommonX86\Microsoft Shared\OFFICE15 or C:\Program Files\Microsoft Office 15\root\vfs\ProgramFilesCommonX64\Microsoft Shared\OFFICE15 (For 64-bit Office installations).
This is because Office 2013 is using the Microsoft App-V (or Virtualization technology) Click-to-Run method.
When you're on the "Start" menu, just start typing "Word" or "Excel" ...the system should start a search and then you should be able to find the programs. If you right-click on the icon, you can "Pin to Start" that way you won't have to search for it each time.
