Invalid parameter "hostname" for SDM command "autoinstall"

I am installing the CRM 2007 with Netweaver 7.0 SR2

I uam using the CD's packed by SAP

51032257 Java Components

51032266 Kernel

51032641 RDBMS

51033089 Installation Maste

51033090 CRM Installation Export

51033093 CRM Java Components

51033265 NW Java Components

Everything was right until the step "Install Java Engine"

The log says

Call of SDM API autoinstall ends with error code 12. Log file content: \n

Invalid parameter "hostname" for SDM command "autoinstall"

I search in google and SDN, and found the following note

Invalid parameter "hostname" for SDM command "autoinstall"

But the advice is not clear for me...

Anyone has another solution??

The box is 64-Bit, I am thinking there are something about it...

Thank you...
