Windows Vista and Windows 7

Currently, London Control is available only for Windows XP. Windows Vista and Windows 7 are not officially supported. However, many customers have successfully installed and run the software on these operating systems. For those who experience difficulty, both London Control and the speech recognition software (SAPI 5.1) can be installed and run using the Microsoft Virtual PC (XP Mode), which is available to those with 'Professional' or higher versions of these operating systems. For more information visit the Microsoft Virtual PC home page.

Error Report: "OLE ERROR 80045078"

This error usually indicates a problem with the speech recognition software in Windows 7. It may be simply that there is no microphone attached which, in Win7, causes the speech engine to fail to initialise. Or it could be that there is no English speech recognizer installed.

If it isn't just the microphone, the error can be fixed by adding the -v command line option to inhibit the initialisation of speech recognition. To do this follow these steps:

1 Find the menu short-cut to the London Control program in the Start Menu.

2 Right click on it and select Properties.

3 In the Target text box, add " -v" (space minus v, without the quotes), so it looks similar to the following (this shows the default path):

"C:\Program Files\DM Aviation Limited\LondonControl.exe" -v

4 Press OK.

5 If any other short-cuts to the program have been set up (on the desktop or start menu), these will need to be changed too.

Now, when running London Control, the voice recognition feature will be disabled.

Error Report: "The system DLL user32.dll was relocated in memory"

A Microsoft security update for Windows XP (KB925902) seems to cause London Control to cease working. It results in an error which begins, "The system DLL user32.dll was relocated in memory."

This is a fault in the Microsoft-supplied user32.dll file, which has been replaced with a new version.

There is a solution available on the Microsoft website, which can be found here: http://support.microsoft.com/kb/935448/

Follow the instructions on this page and download the 935448 package under the heading of "Steps to resolve the problem". Follow the on-screen instructions.

Fault Reporting

If you come across any software bugs or adaptation problems, please let us know. We will log the fault and address it as quickly as we can.

To raise a fault, please e-mail: support@londoncontrol.com.

Please provide as much information as you can to help us track down and fix the fault. Include as much of the following as you can:

  • Exercise number.
  • Simulation time.
  • Traffic rate.
  • Affected sectors.
  • Affected flights.
  • Nature of the fault.
  • Any error reports displayed.
  • Actions carried out immediately prior to the fault occurring.
  • Circumstances that will repeat the fault.
  • Operating system version, processor speed and amount of memory.

Before raising a new fault, you may like to check the log of those that have already been raised and are being addressed. There are two lists, one for Software Faults, and the other for Adaptation Faults.

The lists also indicate when a fault has been fixed, and the version of the software that includes that fix.

When you raise a new fault, we will log it in the appropriate list (you don't need to worry which heading the fault falls under). If you would like to send additional information relating to a fault that has already been logged, please do so.


The June 2013 LCData Update is now available. This brings the adaptation data up-to-date to AIRAC 6/2013 (30 May 2013). Details of what is included can be found on the Updates page.


From time-to-time we issue a patch to correct software faults. These are usually available free of charge for download by registered customers. The latest patch is for version and can be found here.


The first of a new series of tutorials has been added to the website and is available for download from the Tutorials page.

Additional tutorials, covering a range of topics, will be added to the website as they become available.

Adaptation Guide

If you would like to create your own airspace and sectors for London Control, we have created an Adaptation Guide to help you do this. This guide provides details of all the data files used by London Control, and includes a tutorial on how to go about creating new data.

You can download the Adaptation Guide by clicking here.

The guide will download as a zip file. Save this to your hard drive and then extract the file Adaptation Guide.pdf from it. You will need Adobe Reader to open the document.

Please note that the creation of new adaptation files is not a trivial exercise and should not be attempted by the faint hearted!
