Software Deployment

I'm installing IBM Data Studio 2.2.0.2, version that finally avoid the use of the Installation Manager tool. DS comes with an installer developed with Install Anywere, my package is pretty simple, just calls the exe file and points to the .properties files using the -f parameters.
If I run my package manually works fine, but...when I tested the package using SCCM, the installer is taking the System Account, used by SCCM to install the applications to users without administrative rights, instead of the logged user in the PC, that is creating a problem, because send the icons to C:\, instead of C:\Documents and Settings\XXXXX\Start Menu\Programs.

Thanks
