user pref file

Hi,

how to make my personal.ucf is written in the same directory as my personal...UPF (on the network)

I've created:

_USTN_HOMEROOT                     =     $(_USTN_ORGANIZATION)USERS/$(USERNAME)/$(computername)/

_USTN_LocalUserAppDataPath         =  $(_USTN_HOMEROOT)/

but still the personal.ucf is written to:

C:\.....\AppData\Local\Bentley\OpenBuildingsDesigner\10.0.0\prefs  (on the computer where OBD is installed)

what other variable do I have to change too

regards,

Rik
