1) Download and unzip the driver to your computer to the Windows System32 folder. Click HERE

2) RUN Haspdinst.exe with the command prompt as:

haspdinst -purge

(Hint: Type in RUN at the windows 8.1 start up screen)

It will take some time to uninstall the old drivers and once done, it will prompt you.

3) Install the latest drivers with the command as:

haspdinst.exe -i

Then, if all that fails try installing the key diagnostic program:
AKSDIAG.EXE Download this file so that it can be used to install a program that will test if a key is working or not.

If you are running WindPlot in multiple directories then look at the number of the key on the back of your computer. For key numbers smaller than 3000, you will need to copy the file NVWGC16.DLL in your PC-PLOTT directory to your WINDOWS/SYSTEM DIRECTORY to get all programs to see the key.
(NOTE: Keys less than 3000 will not work on 64 bit computers so they will only work on 16 and 32 bit computers.)
