Invalid Firewall Process
 

I downloaded the DisplayLink iPad Software for Windows* V6.3 M1 and tried installing it on my Thinkpad (Windows7, 32bit). But I keep getting the error: "Invalid Firewall Process Mirror Path, or no File Found: C:\Program files\DisplayLink Core Software\DisplayLinkManager.exe".
Is there something missing here? Could someone help me out?
Thannnnnk you!!
