is it possible to activate a thinapp’ed office 2013 by kmspico or kmstools executable

those are activation tools that bypass Microsoft's activation servers. As such they cannot be discussed here.

ThinApp packaged apps requiring license activation such as older (non-Cloud) MS Office or older (non CC) Adobe products are activated using license servers.

See the vmware.com website for details.  NOTE: Many of these are still relevant for newer versions of ThinApp.

The other question to ask yourself (rhetorically) is why are you packaging these apps?  Application packaging with tools such as ThinApp are used for solving App Conflicts, App Deployment Issues, App Update Issues, App Support Issues (for flakey apps), or Support of Legacy Windows apps (such as DOS based apps or Internet Explorer).  

Since Windows based Office applications come from the same source as the Operating System, and quite often everyone needs them, it is easier to just treat them as part of the operating system and do updates on the applications at the same time as the base image.

Hope this helps...
