Loader Not Opening
Who should use this guide
Use this page when you double-click the loader and nothing appears, the window flashes and closes, or the client never reaches the normal ready state.
Before you begin
- Confirm the file still exists in the install folder - Close all duplicate copies of the loader - Check whether Windows or antivirus removed the file
Steps
1
Confirm the install folder is intact
Open the install folder and verify that the loader and required support files are still present. If files are missing, reinstall from a clean package.
2
Check Windows security history
If the file was quarantined or blocked, resolve that first using Windows Security Warning Explanation.
3
Run the loader from a clean local folder
Move the client to a simple writable path such as `Desktop\Mshop` and try again. Avoid network drives or protected system folders.
4
Apply Windows repair checks if needed
If the file still does not open, continue to Common Windows Fixes.

Common questions
The loader worked yesterday and now it does nothing. Why?
This usually points to a Windows security change, missing file, broken update, or path issue.
Can I just redownload and overwrite the folder?
Use a clean reinstall path first unless support told you to patch in place.
The process appears in Task Manager but no window opens.
This still counts as a launch failure. Continue with Windows checks and contact support if the process never produces a visible UI.
