Unzip that file with its complete folder tree to a temporary disk folder. Dependent on your version of Windows you may need to log on as administrator in order to perform the software setup. It is important to perform the setup as administator because otherwise the device driver installation will fail. Only if you intend to use the software without hardware, e.g. as a file viewer, you may run setup without administrator rights. The setup program will install the MultiHarp software including driver, manual, online-help, sample data and programming demos for data access. The setup program will copy the device driver but it will not immediately load it. This is done by the regular Windows Plug&Play device management when you connect the device. Dependent on the version of Windows you may be prompted again at this stage in oder to confirm the driver installation. To uninstall the MultiHarp software you may need to log on as administrator (dependent on your Windows installation). Backup your measurement data. From the start menu select: PicoQuant - MultiHarp v.x.x > uninstall. Alternatively you can use the Control Panel Wizard 'Add/Remove Programs' (in some Windows versions this is called 'Software' or 'Apps&Features') Contact and Support PicoQuant GmbH Rudower Chaussee 29 12489 Berlin, Germany Phone +49 30 1208820-0 Fax +49 30 1208820-90 email info@picoquant.com www http://www.picoquant.com
