Wavelab 9.0.25 update for windows CRASH win 7 64bit

Wavelab 9.0.25 update for windows won’t install on my win 7 64bit system. When you unpack the file, the SETUP.EXE crashes. PS I posted the same error before, but no answer yet: It’s the same with the Cubase 8.5.15 Update win64 installer. So WHAT’s UP Steinberg?, as the older installers like Cubase 8.0.10 are OK. - F
