Ubuntu Linux and Vista can run side by side. If you have Windows Vista installed on your PC you can install Ubuntu Linux right along side it without removing Vista.
InfoStore 3.0 has been tested within Ubuntu Linux and works though a program called Crossover Linux.
PGP is built into Ubuntu Linux and is usable through a variety of tools and utilities.
As for InfoStore and Teletrf working in Vista … we here do not technically support Vista and basically stay clear of it “like the plague” due to an array of reasons. You would do best to test Infostore and any other software on Vista yourself … or just get rid of Vista and opt for Windows XP Pro or Linux.
