normalizePath(path.expand(path) issue


I am trying to help a colleague to install RStudio Desktop, however after installing on a Windows machine through the IT Helpdesk, when opening it this error shows:

Warning message: 
In normalizePath(path.expand(path), winslash, mustWork) : 
path[8]="\\xxxxx/user/home/intl/xxxx/My Documents": Access is denied 

I'm afraid I haven't got more information than this, would anyone be able to help?

Thank you!
