we have installed a host on dozens of computers. But in every case when customer upgrade older OS to WIN10 (not fresh install, just upgrade) connection to this host cannot be established: when I try to connect - double click on icon, icon display "logging on", but hour-glass dissapear after 5 - 10 seconds.
On fresh install of win10 or any other version of win everything works.
I've searched this forum, found that someone has some problem with viewer after win10 upgrade, or another problem was an older version of host ....... we already try re-install host with latest version etc, but still can't connect.
The reason why this happens is that the Host settings are located in the HKEY_LOCAL_MACHINE/SYSTEM/Remote Utilities key and when Windows upgrades, it resets the SYSTEM registry key values. That is why the Host settings are reset including the Internet-ID and access password.
In the upcoming 6.5 update we will change the location for the Host settings and move them into HKEY_LOCAL_MACHINE/Software key instead. So starting version 6.5 this issue will be no more.
Currently, a solution could be exporting the HKEY_LOCAL_MACHINE/SYSTEM/Remote Utilities key and after Windows has been upgraded, importing it back into the registry.
After manually deleting this registry (right, this key still stay in system after uninstall host) and reinstalation of host, we can connect to customer's pc again.
Maybe an idea for the future development of application:
I don't know if it is a problem or not, I'm not a programmer, but it would be good to delete this registry key in uninstallation process of host.
I was about to purchase a license to remotely manage our digital signage hardware that we deliver to our customers, but seeing how your software can't be trusted to work reliably and you still haven't released an update to address this specific issue three months later, I'm afraid I'll have to go look elsewhere.
