Installing Dimension PRO happens that all the install sequence goes until the end, but then any .exe or dll is present in no location.
Tried:
1) clean Install
2) install from file or CW center
3) cleaned Windows register
4) tried two different serial Numbers.
5) always no antivirus or antispam active
Any idea?

Ciao! you can find it, by default in: "C:\Program Files\Cakewalk\VstPlugins\Dimension Pro\Dimension Pro x64.exe" . But, at the beginning, you must check if you can open dimension pro in sonar! and try to install "as administrator".
