Studio 2017 projects.xml location

I have a qouestion

c:\Users\[USERNAME]\Documents\Studio 2017\Projects\projects.xml it is there but user can't save it. Every time the user opens studio project list is empty.

but if i Open projects.xml i see the last project that was open in this file.

why Studio doesn't read this file when opening.

i have tried.

Deleting c:\Users\[USERNAME]\Documents\Studio 2017\Projects folder , could not start studio at all.

Uninstall delete all SDl folders in c:\Users\[USERNAME]\Documents\Studio 2017\Projects

c:\Users\[USERNAME]\AppData\Roaming

 and program files

 

reinstalled Studio 2017 SR1  CU8 and projects.xml is not updated at all.

 

it is not permissions issue because user can save and crate file in c:\Users\[USERNAME]\Documents\Studio 2017\Projects\ folder.

 

where can i change the default location of projects.xml.
