I am trying to install the software on a clone PC with Spec -XPSP3, Pentium D 3.00Ghz & 1G RAM. I have tried download the latest version but still unresolved. The installation almost completes than 'rolls back' and I get a message saying: ' The wizard was interrupted before Pico Technology Software could be completely installed. Your system has not been modified. To complete installation at another time, please run setup again." I have formated my PC, without installing any other software but still get the same message..Already update windows, also cant help. Any advice?? FYI, im having this problem only on this PC.
