Hi all, i recently bought windows vista and was trying to install it on Parallels. But when i tried installing it, i recieve an error saying " Insufficient memory allocated for Windows Vista (192 MB). The minimum amount of memory required to successfully run Windows Vista is 256 MB." After changing my memory in the configuration setting, i recieve yet another error "The memory size specified (256 MB) exceeds the recommended maximum of 192 MB. You must reduce the memory size otherwise you will not be able to start the virtual machine." What can i do to change my memory so i can install windows. I currently run on a macbook with Tiger 10.4.8 with parallels version 3150. Thanks for the help.
