[@Nick H]I downloaded the program again, just in case the original download had got corrupted, it is named differently but the checksum is the same. I installed it in the same drive as the OS with the same result – nothing happens. I uninstalled it and re-installed it again on another partition, nothing doing again. This was after I’d disabled any software that I thought might be causing a conflict, it just doesn’t like my computer, good luck with your future work.
