From Hon Forum, about updating issues.
Quote
Windows specific:
It is important to keep your Windows-installation up-to-date, so use Windows Update and install all the available patches and service packs!
If this doesn't help, try the following:
Select Windows 95 compatibility mode in order to update (de-select it after the updating process has finished):
1. right-click the icon for the program
2. click Properties
3. click the Compatibility tab.
4. set Compatibility mode to "Windows 95"
5. click Apply and OK
Thanks, Valleypunk and Kzanu!
If you are using XFire make sure to quit any instance of it before trying to update.
Open the task manager and make sure no other instance of HoN is running. If there is, kill it.
Run HoN as an Administrator and install it directly into your HDD's root (e.g. C:\).
