CentOS confusion with permissions on root

[blackhole883]

So im running CentOS 7.1 x64 and im attempting to set up a factorio multiplayer server on my VPS

im following the tutorial under Dedicated/Headless server - Linux
at this webpage https://wiki.factorio.com/index.php?title=Multiplayer

at one point the tutorial says to "Check the binary to find if you need any libs installed
and to run this command

#ldd /opt/facrotio/bin/x64/factorio

(i assume its /opt/factorio/ and its just a misspelling)
but instead of telling me what libs i need to install to run the game it instead gives me this error

[root@myserver x64]# ldd /opt/factorio/bin/x64/factorio
ldd: warning: you do not have execution permission for `/opt/factorio/bin/x64/factorio'
linux-vdso.so.1 => (0x00007fff1ff34000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f1355bec000)
librt.so.1 => /lib64/librt.so.1 (0x00007f13559e4000)

/lib64/ld-linux-x86-64.so.2 (0x00007f1355e0f000)

how do i not have permission to do this as root? what am i doing wrong here? and how do i fix it?
