Just a quick update for anyone following this thread, Pierre was able to troubleshoot this issue successfully on his own while we were assisting him.
Pierre had Windows 10 on the system originally and reverted back to Windows 7. When he encountered this issue he ran the ‘Troubleshoot compatibility’ wizard on the DisplayLink driver installation package and the error: 0x80070057 was displayed. When he searched Google for the error it pointed him in the direction that the error could be caused by a problem with the environment variable having to do with the Windows TEMP location. When he made the change as described here --> " ‘Advanced system settings’ -> Advanced Tab -> Environment Variable: I changed the definition of TEMP and TMP to C:\Temp" and rebooted he was able to install the driver.
Our belief is that the previous ‘%USERPROFILE%\AppData\Local\Temp’ directory was corrupted or had permissions broken during the OS change from 10 to 7 and caused the installer not work. We would like to thank Pierre for his great efforts in finding the root cause in this case and sharing it with us.
