I really like Vista, but I've experienced issues trying to install two software programs so far. PerfectDisk and TuneUp Utilities 2007 are both said to be Vista compatible, but I can't install either program to my new Sony laptop with Vista Home Premium. TuneUp Utilities 2007 goes through part of the installation procedure, but stops when a little window appears asking me to 'install' the software. I'm wondering how many others are experiencing issue installing software that is claimed to be Vista certified or compatible.
