I have managed to resolve my issue.
For anyone experiencing the same issue i had;
Do like people said and add the folder etc as an exception on your Antivirus (mines avast) and if your getting the error i had so you don't even get the server.exe file. To get it you'll need to briefly turn off your antivirus (this is what i done) then do the install for you to get a full proper install, then turn your AV back on which will then remove server.exe as soon as you run it. Then go find it in your AV's quarantine and add the file as an exception. Had no issues loading after doing this.
