Query: Be careful to check system requirements

I gave Adobe Photoshop Lightroom only one star because I was not able to install the program in my computer which runs Windows 2000. During installation, the program returned a message saying it required Windows XP to run. Here are the Windows system requirements listed on the box:Microsoft Windows XP with Service Pack 2Intel Pentium 4 Processor768MB of RAM (1GB recommended)1GB of available hard-disk space1024 x 768 screen resolutionCD-ROM driveThose requirement seem very restrictive. No mention of Microsoft Vista. So buyer beware or you may be in for a system upgrade or an unusable program.
