I have just installed Workstation 9.1 on what must be the simplest possible setup - a PC with a laptop linked by a network cable. The OS is XP (SP2) on both machines. The installation was an upgrade from TI 9.0 Home. In addition to the error messages reported by other users at installation (attempt to overwrite newer version of a .sys file etc.), I am having no success with trying to connect to the "remote computer" - i.e. the laptop. Windows explorer can see it fine as can all other apps. Every time I attempt to connect I receive a request for a logon username and password. I am absolutely certain that I have adequate administrator privileges, that the username is correct and the password likewise. Can anyone help? Thanks! I have contacted Acronis help but received no enlightenment so far! I see from earlier threads that I am not the first to have this problem. But I also see alarmingly no clear answer so far.
