NagiosXI Install error

Hi,

I am trying to install NagiosXI as per the below documentation.
http://assets.nagios.com/downloads/nagiosxi/docs/XI\_Manual\_Installation_Instructions.pdf

However its failing in this step:

./E-importnagiosql
NOTE: If prompted, enter the MySQL root password
NagiosQL database appears OK - continuing...
NDOUtils database appears OK - continuing...
ERROR: No files to import - exiting. Were Nagios Core and NagiosQL installed?

Not sure how to proceed from here. Any help is appreciated.

Thanks
HG

Are you installing it in a clean installation or with just using an existing one? What architecture are you using? I have tried installing NagiosXI and it is fine are works great.
