I am trying to install the Pico Scope software on a Dell Studio 1558 Lptop running Windows 7 64 bit OS. I have downloaded the latest software with no luck. The installation proceeds and then a Roll Back is performed. The message indicates the installation process was interrupted. I created a log file as suggested in an earlier post. It is attached. I have successfully used the PicoScope 3204 on a previous machine running Windows XP. Can anyone help?
