We have been moving to a new website hosting provider and it seems like your last message to this thread was posted right during the migration. So I'm quoting it below:
I installed the latest version of the Graphics Card driver (Intel 82945G) and MSXML 4.0. Unfortunately, it has the same problems than before. I tested 5.3 and 5.1 versions.
It is important to note that these machines are industrial HMIs (Human Machine Interface), with TouchScreens from Elo company.
I tried to use a freeware VNC and it is working*.
Is there an error log somewhere that can give me more info?
Answering your question - currently we don't have any more ideas on what could possibly help you with this issue. Nonetheless, I've requested our developers to see if it's still possible to find a workaround. I'll get back to you soon.
1. Uninstall the Host. 2. Open Windows registry, locate the key "HKEY_LOCAL_MACHINE\SYSTEM\Remote Utilities" and wipe/delete it. 3. Install the Host again, preferably the oldest version available in the sticky. 4. Reboot the machine.
