Unable open word / excel in Publisher

Hi all,

I have problem with OLE objects in publisher - ARIS 7.2 
I can´t open word / excel files. 
In Publisher export profiles I have checked "Copy document". 
Word/Excel are not installed in server, only in users workstations.
Names are with small lettres "document1.docx",
In ARIS I can open files, in Publisher I can see but I can´t open.

Please do you have idea where can be problem?

Thank you

Michal Franc
