2.3.4 on Windows 8.1 surface pro 3

[Pitter]

OpenVPN does not start on a.m. installation.
cd to '\Programme\OpenVPN\secrets' failed: Das System kann den angegebenen Pfad nicht finden. (errno=3) [The system cannot find the path]
Exiting due to fatal error

The file 'secrets' was added manually according to an older instruction by the system administrator. It contains the pem and key files.

The configuration in the ovpn reads:

An identical installation with the same files and certificates was installed on a windows 8.1 [VM] and does run without problems.

Could the touch screen version for the surface pro 3 make a difference?
