| Step | Action | |------|--------| | 1 | Verify user has write permissions to %AppData%\MiniTool | | 2 | Rename config.dat (if exists) to config.old – app will recreate it | | 3 | Run sfc /scannow to check for system file corruption | | 4 | Reinstall using the latest clean installer (not a cached version) |
Application fails to launch. Error appears immediately after splash screen.
When trying to start MiniTool Partition Wizard, you see an error message: “Invalid configuration file” – and the software fails to open.
Thank you for contacting support. The “Invalid configuration file” error you’re seeing usually means the software cannot read its settings due to corruption or permission issues.
