error on installing (it sais it's nuke)

[Chip_ro]

I get this error:

ERROR
You seem to be trying to install the standalone Coppermine into your Nuke portal.
This version can only be used as standalone!
Some server setups might display this warning even though you don't have a nuke portal installed - if this is the case for you, continue with the install. If you are using a nuke portal, you might want to take a look into CpgNuke or use one of the (unsupported) coppermine ports - do not continue!

I am not using any nuke or anything actually - it is just nuke. I click to continue and after i fill in the datat (database, user, etc) is brings me back to the same message (the one above)
