MTink

I installed mtink-1.0.1-1.i586.rpm on a 32-bit Desktop PC running SuSE 9.1 I would like to install MTink on my laptop as well. But my laptop is 64-bit architecture and runs SuSe 9.3 Will the same MTink version be OK ? When I install the rpm file: # rpm -Uvh <filename> Should I be root or can I be a regular user ? Thank you so much. Maura
