Richard Ay，

I finally solved the problem.

I guess that problem is something wrong with graphics,because the prepip.exe is based on graphics, and any graphics related modules of CII 2017 all can't work.

I found this morning my computer is equipped with two video cards, one is AMD Radeon R5 430 and another is Intel(R) HD Graphics 630 on mainboard, if i stop anyone of them, CAESAR II 2017 revive and prepip.exe can work again.That's
great!

Thank you! mariog and Richard Ay.
