MaintenanceTool:- Uninstallation of Qt Version Does Not Remove It from Device

Environment:

• Operating System: Windows

• Qt Maintenance Tool Version: 4.9.0

• Qt Version Affected: 6.7.3 and 6.5.8

Description:
I encountered an issue where uninstalling a specific Qt version does not actually remove it from the system. Even after completing the uninstallation process, the supposedly deleted version remains on my device. When I restart the Qt Maintenance Tool, the version I attempted to remove is still listed as installed.

Steps to Reproduce:

1. Open the Qt Maintenance Tool.
2. Uncheck a specific Qt version to uninstall.
3. Proceed with the uninstallation process and wait for it to complete.
4. Check the system directory where Qt is installed and notice that the files are still present.
5. Restart the Qt Maintenance Tool.
6. Observe that the uninstalled version is still listed as installed.

Expected Behavior:

• The selected Qt version should be completely removed from the system.

• Upon restarting the Qt Maintenance Tool, the uninstalled version should no longer appear as installed.

Actual Behavior:

• The uninstalled version remains on the system.

• Restarting the Qt Maintenance Tool still shows the deleted version as installed.

Additional Information:

• I cleared cache before attempting to uninstall it again.
• I have sufficient disk space and administrator privileges.

• No error messages were displayed during the uninstallation process.

Please investigate this issue, as it prevents proper version management using the Qt Maintenance Tool.
