TypeError: user has no properties (in script NW_ABAP_OneHost|ind|ind|ind|ind, line 14533: ???)

Hi,

i got problem on installing netweaver 7.3.

a message box appears during installation

An error occurred while processing option SAP NetWeaver 7.0 including Enhancement Package 3 > SAP Application Server ABAP > MaxDB > Central System > Central System( Last error reported by the step: TypeError: user has no properties (in script NW_ABAP_OneHost|ind|ind|ind|ind, line 14533: ???)). You can now:

• Choose Retry to repeat the current step.
• Choose Log Files to get more information about the error.
• Stop the option and continue with it later.

Log files are written to C:\Program Files/sapinst_instdir/NW703/AS-ABAP/ADA/CENTRAL/.

anybody can explain what this means ?

thanks alot
