Still got the 1.4.6. so i have uninstall all the client. and redownload the laucher. But now, its says "impossible to execute a file from a temporarie folder. Aband

Greetings.

The error occurs because the installer cannot run one of its temporary files due to access being denied.

Main Reasons:
- Antivirus / Windows Defender (Most common cause)
- Security software blocks execution of files from the temporary folder (%TEMP%). This is a common false positive with installers.
- Insufficient permissions on the Temp folder
- The current user does not have full rights to read/execute files in the Windows temporary directory.
- Problems with TMP/TEMP environment variables
- The temporary folder path is set to a restricted or non-existent location.
- Running without Administrator rights
- The installer needs elevated privileges but was not launched as Administrator.
- Corrupted or damaged installer file
- The setup file itself is incomplete or got corrupted during download.
- Windows User Account Control (UAC) or folder protection
- Strict system policies or protected folders preventing execution from Temp.
- Conflict with other security tools
- Sandboxing software, application control, or endpoint protection solutions.

Recommendation:
Please check that your Windows system does not have any of the problems listed above. Temporarily disable your antivirus, run the installer as Administrator (right-click > Run as administrator), and try again. Restarting your computer before retrying can also help.

If the error still appears after checking these points, please reply with the following information:
- Your version of Windows
- Which antivirus software you are using
- Did you uninstall your previous launcher version with your Windows built-in uninstaller?
