#### UPDATE 30 SEP 2019 - 1300Z ####

Here's where we are at the moment with outstanding issues identified so far:

- [Resolved] I am getting Enigma Protection Error in Windows 10 and Prepar3D v3.

Latest v1.41 release should not have any Enigma Protection Errors any more.

- [Resolved] My Concorde-X loads with black / blank screens and I see no gear in the external model.

If this is a first-time Prepar3D installation, ensure you have installed SimConnect redistributables as well.

Check that there is no simconnect.cfg anywhere in the "My Documents" folder configured to only use SimConnect remotely.

- [Resolved] Validation error 815 in P3D and/or FSX:

This issue has been resolved. Use the redownload service to download the latest Concorde-X installer. Uninstall the previous version, then install the new one.

- [Resolved] Validation Error 1044 and then the Sim closes.

A: First ensure you are running the sim *as ADMINISTRATOR*. If that's the case, try the following steps:

  1. Uninstall it and delete any remaining folders (FSLabs/Concorde and the three FSL aircraft folders in <SimRoot>\Simobjects\Airplanes.
  2. Delete the Flightsimlabs folder from c:\users\<yourname>\appData\local.
  3. Reboot.
  4. Install the Concorde-X.
  5. Check that your DNS name servers are set to and (Google's public name servers) like this:


- [Resolved] Installer crashes after serial number is entered:

Please uninstall ALL Microsoft Visual C++ Redistributables from your computer and download and reinstall from here.

- [Resolved] FSX (legacy or Steam) API.dll (or FSUI.dll) crashes:

This issue has been resolved. Use the redownload service to download the latest Concorde-X installer. Uninstall the previous version, then install the new one.

- [Resolved] FSX full screen DX10 mode ADI redrawing issues:

This issue has been resolved. Use the redownload service to download the latest Concorde-X installer. Uninstall the previous version, then install the new one.

- [Resolved] FSX Steam mouse panning and alt- and shift-key or other keys inoperable:

This issue has been resolved. Apparently, this is caused by the Steam overlay that interferes with in-game mouse and keyboard handling and conflicts with advanced event handling techniques. We continue to be somewhat surprised that this is not noticed in any other add-on, but it is true that the Concorde-X complexity is on the top-end of the scale. Unfortunately, our emails to Dovetail have gone unanswered on this topic, but one of our FSX SE customers going by the username of Wauzi4 has found a solution:

1. On the upper left at Steam click on the dropdown menu "Steam" and select "Settings".

2. On the left column select "In-Game".

3. Untick the checkbox "Enable Steam Overlay In Game".

4. Now restart Steam (Go to the taskbar, make a right click on the Steam logo and close it.)

- Various small fixes in functionality:

  • Support for P3D v3.4
  • Fix for Engine start / 15% N2 in P3D
  • Fix for save/load flight functionality in P3D
  • Improvements to MAX CRUISE (to prevent descending unnecessarily)
  • Autothrottle improvements
  • Autopilot VOR mode improved
  • Autopilot VERT SPEED mode improved
  • Autopilot GO AROUND disengagement with HDG HOLD
  • ADI FD flag logic corrected
  • Yellow Hydraulic LP warning on gear extension now random
  • ICOVOL lower rudder indicator fixed
  • VFE Aft Trim issue fixed
  • Missing 'Alert Height Cat 3' call out fixed
  • Glareshield spotlights in VC added
  • Engine Idle Switches auto latch to High at 60kts
  • VFE fixes for acceleration climb logic
  • COM Radios now show 6 digits
  • Throttles set to full power with reheat (in flight)
  • Possible fix for IAS HOLD pitch up issue
  • AI airplanes jumping like crazy issue
  • INS freezing issue
  • Options not properly saving issue

These issues are all resolved in the latest installer which is available in the redownload service.

- [Resolved] eSellerate eDP still showing Concorde-X v1.2 download:

As of February 2016, we have phased out the eSellerate download protection system and replaced it with our redownload service instead.

- [Resolved] FSX Steam standalone (no FSX legacy installed side-by-side) installer issues:

Simply visit the redownload service to download the latest v1.41 installer - it should fix this issue as well.

- [Workaround] P3D running out of memory at high resolutions (more than 1920x1080) issues:

Edit Prepar3d.cfg and change PANEL_STRETCHING = 1 to PANEL_STRETCHING = 0. Then, start P3D in windowed mode at a lower resolution, load the Concorde-X and then expand to full window mode.

- [Workaround] Concorde-X stuck with hourglass spinning when loading:

If you own Milviz F-15E or other Milviz products, some customers reported that disabling the Milviz_pack.dll entry in dll.xml can restore Concorde-X functionality (link here).

- [Workaround] Concorde-X crashes with 100% resources loaded:

Please go back to NVidia drivers 376.33 as they are confirmed to work perfectly with our product line.

Thanks for your support, as always!

I'd like to kindly request that if you have support questions that have not been asked in other posts already, please start a new thread - don't post here. In fact, I'll lock this thread for clarity.

as you may have noticed, I've cleaned up the thread and edited the text to bring the topic up-to-date. The latest v1.31 Concorde-X installer is now available through our new FSLabs redownload service, it's the most current installer.

Whenever we have news on updates, I'll be updating this post further.
