I have been using oncourse on my desktop PC. Have now got a brnad new laptop that I will use instead of the PC. Trying to install server on laptop and am getting message "The JVM could not be started. The maximum heap size (-Xmx) might be too large or firewall tool could block the execution." I have turned off the firewall and anti-virus when installing. My laptop is 2.60GHz processor, 4GB RAM, 64-bit operating system. I have updated Java to 7 and also installed the 64 bit Java. I don't know what else to try. There also seems to be something going wrong when i hit "next" button to begin the installation as the green bar only gets about half a centimeter along then the window tells me it has been installed and shortcuts created. This takes about 4 seconds! Doesn't seem right. Appreciate any help you can give me as at a loss what to do now.
