Oracle 11g client / oracle 10g express edition in one computer

Question

Hi All,
I already have Oracle 11g Client installed in my computer. I wanted to Install Oracle 10g Express Edition in the same computer. So that I shall work with that even when I am not in the network. My Question is : Will installing both of 11g Client and 10g XE will cause conflict in my computer or is it ok to install both. Any suggestion/information is appreciated.
Regards,
RRR
