Most people install 32 bit linux so flash and java work. 64 bit windows and linux have severe app compatibility issues. I am suprised that it refused to install on your system ... Either way I would say use the latest version if at all possible (SuSE is up to 10.1) and see how things work. To be honest Mepis is not the most supported flavor of linux. For you I would suggest the latest SuSE, Fedora, or Ubuntu for best results.
