Hi Andrey,

Writing to  /Application on macOS or "Program Files" on Windows requires 
admin privileges. It is very uncommon when application stores temp files 
or setting files modifiable by user inside installation folder. For temp 
files I will recommend to use system provided temp folder. For setting 
it will depend on OS type.
