    Farhan_Masood,

    I would try to install all possible windows updates available (start/check for updates).

    You might have to restart and check again several times if you have not updated your laptop in a while.

    If the problem still exists after that, try reinstalling EMTP. Make sure to have the admin right when you do that.

    If all that does not solve your problem, please contact the technical support.

    Thanks

    Henry
