I also tried these tips, but to no avail. But let's be honest, if I buy something, I can assume everything will work without a hitch, right? Now I have to install via VPN, disable the firewall, delete folders, and so on. I did that, but to no avail. My PC meets all the requirements, has plenty of space, and your own software says it's out of space or has a corrupt file. The result is that the software can't be installed. What now?
