Solved: Nothing happens when clicking on the NWC 2.75 Preview installation file 2015-07-14 03:56 pm Hi,I recently encountered difficulties installing the latest NWC 2.75 previews on my Windows Vista.Problem: When clicking the installation exe file, the hour-glass appeared for a few seconds, and then nothing happened.After searching through various websites, I came across a fix for this:1) Right-click on the exe file2) Select Properties->General Tab3) Where it says at the bottom "Security: This file came from another computer and might be blocked to help protect this computer." click on the Unblock button4) Click on Apply, then Ok5) Click on the installation exe file againProblem Solved!Regards,Ian Quote Selected
