windows can not access the specified device,path or file.You may not have the appropriate permission to access the item
then when it disappears from my folder Ive got everything up to date but still so any ideas

Try downloading Horizon from this link: https://www.horizonmb.com/client/v2/latest.php, then try installing. If it still gives you problems try right clicking on the setup installer, go to properties, and click the Unblock button near the bottom right corner, and then try installing.
