Driver Planner can be installed on any version of Windows from Windows98 onwards. If you are installing it on Windows XP or newer you will need to be logged on to the PC as Administrator, or in Windows Vista or newer you will have to right-click the Installation Wizard and choose Run as Administrator.
The Trial Version is called DEMO.EXE
After clicking the download link, choose either Run or Save As (if you choose Save As, you need to run the downloaded file from the location you saved to). You may be asked to confirm your actions; click affirmatively to proceed.
The Installation Wizard will open.
Click Next > to work through the installation process. If you accept the default settings then at the end of the installation you should see an icon for Driver Planner on the desktop and also in the Start menu.
