i dont know if it's related to that i've downloaded and installed other versions of CST Studio Suite (u know with crack which would do something with the license manager) ,and then i deleted them cause i find the free student version, but now this problem occured both the student version and other versions.

by the way it will pop up a window like cmd for one second then disappear before the "update license service" problem happen

p1 the problem during the installation

p2 p3 when i open the license manager ,it has some problem too
