Mybook live 3TB - Unable to run exe files from mapped networkdrive (win 8.1)

Hello i the forums

Yesterday i switched from windows 7 to windows 8.1. 

I have all my application install files on a networkdrive which I mapped to Windows 8.1. The problem is, that i get an errormessage when I try to execute the program. 

I have tried installing Winrar, VLC, dropbox and more. But all come up with an error in the lines of “wrong parameter error 87”.

Strange thing 1: If i copy the file to my dashboard and execute it from here - there is no problem.

Strange thing 2: I ran the steam installer from the drive, and this it could install no problem, hmm?

Could anyone point me in the right direction to fix this issue?

I have a WD mybook live 3 tb with latest firmware.
