CAD not working

Post by dominikd »

On machines running windows vista, we have the problem, that CAD is not working. We always get the following error: "Ctrl-Alt-del require service, no permission" as soon as we send CAD. Vista files are downloaded, cad.exe is present in uvnc directory, uac is enabled, uvnc is running as a service.

1. ctrl+alt+del for work with uvnc on vista/7

schook.dll is optional and increase update speed screen change on vista/7

* system service (running before windows logon/welcome screen)
send ctrl+alt+f4
