Coldfusion installer succeeds, but with no /bin/ directory

I've just tried reinstalling a CF9 server, but the installer finishes with "11 NonFatalErrors", and there is no /cf-root/bin directory.

This means I can't run /cf-root/bin/coldfusion start so I can't run the server. I've tried installing it twice and had no luck.

I installed as root from /opt/, to /opt/coldfusion9, using the ColdFusion_9_WWE_linux64.bin file downloaded from Adobe today, and with permissions set to 777 on the file.

The /cf-root/coldfusion9 folder is missing other directories as well, for example there is no logs directory. There also seems to be coldfusion and cfinfo files in the cf-root folder, these look like they should be in the bin folder.

So I have the following:

/cf-root/coldfusion9/coldfusion
/cf-root/coldfusion9/cfinfo
/cf-root/coldfusion9/cfstat

Instead of

/cf-root/coldfusion9/bin/coldfusion
/cf-root/coldfusion9/bin/cfinfo
/cf-root/coldfusion9/bin/cfstat

I'm sure I need to post more data here if anyone's going to help but I'm not sure where to look next.

I'm running Red Hat Enterprise Linux Server release 5.6 (Tikanga)
