The thing I’m seeing…one of the most common features of those complaining about 4.5 not working…32 bit systems. 4.5 is just at the edge of being able to be run under a 32 bit OS…and in some cases over it.
Time to face it, folks, 32 bit is DEAD. Upgrade to 64 bit and save yourself a host of headaches, because I seriously doubt that DS is the only piece of software, if upgraded to the latest version, that is giving you one. Software has progressed beyond 32 bit, it’s time to make your hardware do so, too. All major software and many games are 64 bit.
