LoginInGuest() issue with VIX_LOGIN_IN_GUEST_REQUIRE_INTERACTIVE_ENVIRONMENT option

Hi,

I'm having problem with the LoginInGuest() function when using the VIX_LOGIN_IN_GUEST_REQUIRE_INTERACTIVE_ENVIRONMENT option. Here's the code written in C#:

jobHandle = vmHandle.LoginInGuest(guestUser, guestPassword, Constants.VIX_LOGIN_IN_GUEST_REQUIRE_INTERACTIVE_ENVIRONMENT, null); vixError = jobHandle.WaitWithoutResults(); if (vixLib.ErrorIndicatesFailure(vixError)) { throw new VMRobotException("Error when logging on to guest OS. Error code: " + vixError); }

every time this is run, it returns error code 3034 VIX_E_INTERACTIVE_SESSION_NOT_PRESENT (The specified guest user must be logged in interactively to perform this operation.) Any one help please?

BTW, I'm using VIX 1.6.

Thanks!
