FFXI wont install on win7 PoL

[Strife]

Hi I downloaded the win 7 compatible version of PoL but when I try installing FFXI it says it cannot install as PoL is not installed. I have run as administrator, turned off my anti-virus, tried updating PoL, re-downloading, uninstalling and reinstalling PoL and installed PoL from my install disc (it installs to the same file path as the win7 compatible version c/program files (x86)/playonline. FFXI will install but PoL won't launch). I am trying to install using the "autorun.exe" and "setup.exe" files from the disc marked FFXI disc 1 as instructed by the FF website. I have followed the instructions on the FFXI website for installing on win 7 implicitly but I still can't get FFXI to install on my new win 7 computer. What am I doing wrong?

Addendum: By the way your tech support form isn't working either.... Today I got a different form that worked.
