Hi Murtaza,
I'm a little confused!
Is the system on a Windows or a Unix server?
The paths should be:
WINDOWS: <install root>\SAP BusinessObjects\setup\packagestemp
LINUX/UNIX: <install root>\setup\packages (root is 1 level above sap_bobj).
Also, if Windows, and if G: is the install drive, is G: a local drive or a shared/mounted drive?
