My settings work for all downloads except yours?
Your download is the only one with differant installer? Compare to all your downloads and right click on them, properties. HP Tuners is the only one differant ie no run as admin is one although there are a lot. Although I have never had to use Run as Admin option. Point is if you right click HP Tuner download file, properties HP Tuner it is differant then any other downloaded software which are all the same of which I have no issues?
Also right click properties on any download. HP Tuners is the only one on General tab to have Type of File and Opens with. BTW mine says to open with Windows installer.
If you look at type of all downloaded software they all say Application. HP Tuners says Windows Installer Package.
Really I hope that helps you.
I'm not going to change my computers just for your software then have issues with the rest of the world. HP Tuners is the only download differant then the rest of world is using.
Also installed a HP Tuners folder and error changed from 1303 to 1307.
