Installation and Uninstallation

When installing or uninstalling Composer in a Windows XP Professional or Windows Server 2003 Standard Edition environment, the prompt reboot may appear. After the reboot, the following message appears: There are some pending operations and the system needs a reboot. The target computer does not meet some mandatory requirements. Subsequent reboots result in the same behavior and you cannot install Composer on this machine. This is a result of pending reboots from other installations. To correct this situation:

1. Open the Registry editor.
2. Remove the following key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations
3. Install Composer.
