    @Ganeshmurthi,P,Prakash,QAW9 C

    It seems that the error message is explicit, and the Windows server O/S is not going to allow the program or VS to execute, because an O/S security policy is being violated. It also explicitly is stating what needs to happen to allow the program or VS to run hosted by the Windows server O/S concerning security policies.
