Fix for identify install location and configuration location

[serjiokov]

Require to test:
case 1: If the product is installed in a public location (where the access rights is enough to create files/folder), the configuration will be in the same folder as the installation (unpacked)
case 2: if the product is installed in a system location C:/Program Files/... or other restricted user area, the configuration will be in a common location
~/user/APP_DATA - WinOS
~/Library - MacOS
~/.local/share - Unix
