Is there anyone using Straton with SVN client?

I got problem with it and find no instruction in Straton Help. After installation of Zenon 7.60 on my PC (Win7), I created a Staton project and enabled the Version Control in Project Setting. There I can see the current Sub version control that is running on my PC (SVN client) and link Staton project to my online repository. 

My co-worker also installed Zenon 7.60 on his PC (Win10) and tried to enable Version Control in Straton Project Settting. But he could not see the current Sub version control (SVN client) that is running on his PC.

It make me quite confused. I hope anyone from this forum could give me some tips.
