My configuration is Parallels 5.0 (upgraded from 4.0) running Windows XP Pro SP3. I have been using the Kaspersky INS 2009 (Version 8.0.0.506(a)) by Parallels, but the license period has expired. I also have a separate multi-user license for Kaspersky INS 2010. Can I install the Kaspersky INS 2010 under Parallels in the VM? Are the two products compatible? To install the Kaspersky INS 2010 should I first uninstall the expired version provided by Parallels? Thanks for any help.
