Error on installing HP Photosmart D71000 Series

I have been trying to hook up my device with HP Photosmart D71000 series.
However, while trying to install the software, I keep getting this error message; software cannot be installed using the ‘Run as’ command.
It also suggests that it should be logged in with admin privileges, tried it but the same error message pops-up.
I have been searching the internet on how to solve this problem but found nothing.
Can someone help me?
Thank you!
