To fix this problem two registry settings must be adapted/added. Note only administrators have the rights for these 2 keys. This can be done:

Automatically: by running MoLabVinciLabFix. Download the file here and run on your computer.



  1. Start menu at left-bottom: “Windows System” -> right click on “Command Prompt” on move mouse on “More” and select “Run as administrator”.
    In the search box type “cmd” on the “Command Prompt” that appears in the list above you can right click and select “Run as administrator”.
  2. Copy and paste these 2 commands to run them:

REG ADD HKLM\SYSTEM\CurrentControlSet\Services\RapiMgr /v SvcHostSplitDisable /t REG_DWORD /d 1 /f

REG ADD HKLM\SYSTEM\CurrentControlSet\Services\WcesComm /v SvcHostSplitDisable /t REG_DWORD /d 1 /f

  1. Reboot the pc.

It may be necessary to update the firmware of an interface from time to time. CMA occasionally releases improved firmware versions to improve an interface’s interaction with the computer, a tablet or one or more sensors. To update an interface, it needs to be connected to a desktop or laptop and Coach 7 needs to be started.

For some interfaces Coach 7 is able to automatically detect if an update is available. You will receive a notice about a possible update when initialising the interface for a measurement activity. Simply agree to update the interface and Coach 7 will perform the update. After a few moments the interface is ready and you can continue with the measurement.

Other interfaces need to be updated manually. Start Coach 7 in Author mode and select “Tools” in the menu at the top of the screen. Select “Firmware update”. A new window will open. Select the interface that is connected to the computer that you want to update and select the most recent firmware version. Perform the update and then continue as planned.

VinciLab runs a version of Coach 6 that was specifically developed for Linux machines. This is a standalone version that is not related to the version for Windows (Coach 6) or the version for Windows and Mac (Coach 7). It is therefore not possible to update VinciLab to Coach 7. As a standalone datalogger, VinciLab will look and feel different than Coach 7 on PC or Mac for the coming time.

It is, however, possible to use VinciLab as an interface for Coach 7. When connecting VinciLab to a computer using USB or WiFi, Coach 7 will detect VinciLab and initiate it as an interface. This way, you can do measurements In Coach 7 on PC or Mac using VinciLab.

Whenever updates for VinciLab become available, these will be distributed via our update servers. VinciLab needs to be connected to the internet and the update needs to be initiated manually. This can be done in the “Settings” menu.

There can be a couple of reasons why Coach fails to communicate with VinciLab:

  • The VinciLab driver is not installed correctly on your computer. After a successful installation, VinciLab should be visible in the Windows Device Manager under Network adapters. If the driver wasn’t successfully installed, it can be installed manually in Device Manager by specifying the USB VinciLab driver setup files. Details of this procedure can be found in the VinciLab Users’ Guide.
  • The USB cable is not connected correctly. You have to connect the provided USB cable correctly and use the USB connector that is meant for communication, and not the USB connector meant for additional powering.
  • A computer firewall may cause communication problems (via USB or Wi-Fi). Make sure that the Coach executable (Coach32.exe in Coach 6, Coach7.exe in Coach 7) has permission to use the ip-address of VinciLab, and ports 22 and 1111 – 1116 are opened. If connected through USB, the VinciLab gets an ip-address in the range – For a wireless connection, the address depends on your network configuration. Please note that when using the USB cable, it may take a while before VinciLab gets its final ip-address.
  • Some anti-virus programs can block communication between Coach and VinciLab. Give Coach permission for such communication.

In general: if an attempt to connect VinciLab in Coach fails and you change the hardware settings in Coach, restart VinciLab and try again to connect.

There appears to be a problem with some (newer) sensors where the EEPROM cannot be read properly by the CLAB. A solution for this hardware problem is yet unknown. At the moment we advise you to manually select unrecognized sensors from the sensor library.

The €Lab interface is only powered through USB, which places a limitation to the maximum power consumption. This may also be dependent on the computer the interface is connected to. Some sensors needs more power (for example the Force sensor or the CO2 sensor) and when such a sensor is connected to €Lab and the USB port does not provide enough power then the sensor may not work properly or may not be automatically recognised by the Coach software. First select manually the sensor from the Coach Sensor Library and check if this solves the problem.



There is a hotfix available for Windows 7, Vista Windows Server 2008 R2, Windows Vista or Windows Server 2008, and a separate hotfix for Windows XP.
After installation of the hotfix use the Device Manager to uninstall the VinciLab driver while VinciLab remains connected to the computer via the USB cable. Then disconnect the USB cable from the computer and connect it again to use the new Microsoft RNDIS driver.

Wireless measurement is possible with the VinciLab, WiLab and CLAB interfaces. The VinciLab is an independent datalogger that can be connected to a computer and Coach to exchange data. The CLAB is a datalogger to which a measurement program can be uploaded via Coach. The measurement itself can be carried out wirelessly and the data can be transferred to Coach at a later time. WiLab is an interface that can connect to a tablet using BlueTooth.
In addition, a wireless interface is being developed that uses Bluetooth to communicate with a computer / mobile device (within a 10 meter range).
