don't know if you are on a MAC or PC...I can only speak to the PC side of it.
If you are using DazInstaller, make sure it has all your paths loaded correctly. By default, it will put everything in the 'C:\users\public' folder unless you tell it otherwise. Alternatively, you can use one of the installers included in the package. if you have a 64 bit system, then use "DS4_MeasureMetrics_1.4.0.123_Win64.exe", otherwise use the other one. Using the installers should allow you to point it in the right direction for your installation.
