This may be because you don’t have the correct user rights to modify the installation folder.

Please ensure that you set the platform to run as an administrator as otherwise it will run with a normal user’s privileges.

If you run the application with a normal user’s privileges, you won’t have the permissions to modify the MT4 files and, therefore, to save any changes in the settings.

Based on this, please do the following and then try to use the platform again:

1. Right-click on the MetaTrader 4 icon that you have on your desktop
2. Select ”Properties”
3. Select the ”Shortcut” tab
4. Click on ”Advanced”
5. Tick ”Run as an administrator”

If this doesn’t solve your problem, you may contact your account manager from the FxPro Official Website.
