Hello everyone. I'm experiencing a problem when I try to install my CATIA Student Version. My computer is running a 64bit operating system with 12 gigabytes of RAM but I keep getting this message saying that I need to launch something from a higher command level whenever I run the setup. I've had V5R25 on this computer for the past two years without any issues and all of a sudden no version off of the download center will install. They all have the same error message pop up. Has anyone else had any problems with this or have any ideas? Thanks.
