also un installed it deleted all data app of horizon and then re downloaded it still cant get it to work ?
any solutions ???:worried:

Try redownloading .NET framework 3.5 and 4

EDIT: Finally Beat You Steve.

Check if you have any Windows updates and take them if you do.

my system is using 4.5

no updates

Go to your Control Panel > Programs > Programs & Features and check if you have 3.5 installed. If you don’t, get it here:http://www.microsoft.com/en-us/download/details.aspx?id=25150

downloaded it still not working

Try this. Go to settings > control panel > programs, and open Turn Windows Features On or Off. Make sure your .Net Frameworks are turned on. If you expand them by clicking on the + box you can check to see if anything is unchecked, try checking those off and see if Horizon will work now.

all checked still not working

I know you’ve already reinstalled, but try again after downloading from this link: https://www.horizonmb.com/client/v2/latest.php

done that still no joy
