Inactive Installation Button - Running SetupArcheAge.exe
It could happen when there is not enough disk space to install,
or the path to the setup is specified as root directory.
Please free up disk space [more than 60GB] by running Disk Cleanup and deleting unnecessary programs or create subfolder
[e.g: C:\ArcheAge, it is because the button is inactive in case
you only select root directory such as C:\ and D:\] and try again.
