Copied from the Vogone Product Description page. The line I bolded is self explanatory.

"Computer Requirements
A Windows/PC computer (not Apple/MAC) running Windows Vista, 2000+SR4, or XP (home/pro/media)+SR2 with .NET Framework v1.1 or higher NOT Windows 98SE, ME or NT, a 733MHz or faster processor (Celeron, Pentium 2,3,4 or AMD Duron or Athelon). Duo-core and Duo 2 core processor motherboards are proven and MTU ships these in our Laptops. System RAM: if Windows runs so will Vogone. Have at least 500MB of free hard drive space (~40MB/song). Internet connection or USB Memory Stick or Floppy Drive is required to install, but not to run. To import songs as WAV files and write vocal reduced WAV files to a CDR disc, you will need Microstudio or an equivalent program, and an MTU or equivalent CD/DVD burner. You can install and run Vogone Lite on one computer, and the Full version can install on a second.

NOTE: Version 3.102 or higher requires at least a 733MHz processor to play and adjust while you listen. However, it will export a vocal reduced file to the hard drive with any speed Pentium class computer."
