Margin Master
Alert users when settings folder lacks write permissions
Shipped in Margin Master 2026.901.28986 · September 1, 2026
Added a startup check that detects when Windows permissions prevent Margin Master from saving settings files (like DatabaseConnections.json) in its ProgramData folder. Previously, this surfaced as "User cancelled" errors and caused the database setup to loop on every launch; now the app shows a clear error message explaining the permission problem and how to fix it.
What changed
If Margin Master can't save settings because of Windows permissions, you'll now see an error message at startup that lists exactly what's wrong and tells you to ask your administrator to grant Modify access to the settings folder.
The error message shows exactly which files can't be written and tells you who to contact to fix the permissions.
