Fatal Error: At least one port in the range 4520-4539 must be open

199 Views

Apparently this is a common issue. I have made sure all ports are open.

I have also extracted the .zip to the root of C: and run Setup.exe as administrator as suggested in the numerous other threads.

Still not working and getting that error every single time across multiple machines.
