Ensure the update script targeted the correct registry hive. Virtual keys for 64-bit applications running on 64-bit Windows operating systems must load into the exact system control path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\MultiKey\Dumps\
Before installing new files, you must completely remove the old emulator instance to prevent driver conflicts. Open the as an Administrator. Navigate to your old MultiKey folder.
