DisplayLink driver installation error on Dell Latitude 3450

[shepherd901]

Hello I've been trying to install the displaylink driver onto my laptop Dell Latitude 3450 and having hard time,

when I first execute the driver Windows 8.4 M0, it shows the attached error message (1) but it proceed with opening the installation program but once I push the installation button it shows another error message (2) which says "there was an error while reading the file: C:\.......\displaylinkManager.exe. check whether the file really exists and is accessible. (it's in Korean and I translated it in English)
FYI I'm still using windows 7, 64 bit. in all the other computers I'm using, I installed this driver and using multi monitors without any issues at all.

I really need this multi monitor system and hope someone could help this out.

thanks for your help in advance,
