Locating the logfile of a software module

If you encounter an issue with any software module, e.g., some features not working correctly, it is of great help for us if you attach the logfile of the according software module. This will help us to identify and solve the issue.

The logfile (logfile.db) is located in the corresponding module folder. To open the folder, right click on the module in thaTEC:Core and select Open module folder:

Add/update modules without internet connection (offline updates)

If you are using a PC without an internet connection in your lab, you can still conventiently add and update all our software modules using a second PC with an active internet connection. To do so, just follow the description below.


thaTEC:Core must be installed on both PCs. For this, download our (offline) installer from the Download section of our homepage.

Step 1: Download/Update module database

Using the PC with an active internet connection, select Modules => Download modules to local folder from thaTEC:Core’s menu bar and select the target folder (e.g. a USB stick).

Reduce download time: Before starting the download, thaTEC:Core will check all files that are already present in the selected folder and compare them to the files on our server. Thus, by always selecting the same folder for the downloads, the download time can drastically be reduced since only updated files are being loaded!

Step 2: Update settings

After the download has finished, transfer the downloaded files to the PC without internet connection (i.e. connect the USB stick to the PC). To use the offline database, you need to adjust the according settings. For this, select Modules => Update settings from the menu bar:

Subsequently, selet Offline from directory as update method and select the according folder where the downloaded database are located (i.e. the USB stick) and apply the settings:

From here, you can update and add new devices from our database identical to the case with an active internet connection.

Error: lvanlys.dll – Resource not found.

If you are using an AMD (inparticular AMD Ryzen) processor, you might encounter this issue during the startup of some of our software modules like, e.g., thaTEC:OS or the DataInspector.

With recent versions of thaTEC:Core, this issue is solved automatically after eventually (once) granting Admin rights after the startup of thaTEC:Core.

In order to solve this issue manually, you need to add a new environmental variable named “MKL_DEBUG_CPU_TYPE” with a value of “5”.

To do so, please follow this procedure:

  •  Press the windows key, type “environment“, and select “edit the system environment variables“.
  • In the System Properties window, click on the “Environment Variables” button.
  • In the upper “User Environment Variables” section, select “New“.
  • Insert “MKL_DEBUG_CPU_TYPE” in the field “Variable Name“.
  • Set “5” as “Variable Value“.
  • Apply the changes and reboot your PC.

If you still encounter this issue, please contact us under contact@thatec-innovation.com

Add a network device to the VISA device list

Devices connected to the PC via USB or GPIB are usually automatically detected and can be selected from the dropdown list of the Device address control. Devices which are connected via ethernet are not detected automatically but the device adderss must either be entered manually in the form

TCPIP[board]::host address[::LAN device name][::INSTR]
e.g. TCPIP0::

or the device can be added to the device list using NI MAX. For instructions and more information, visit


Open a remote support session

Developing software modules for your hardware usually requires a debugging process. If the according PC is connected to the internet, the easiest way to debug the software is to schedule a remote support session with us so we can directly access your PC and debug the software modules.

Please note that no additional software needs to be installed!

To open a remote support session select Support => Open remote support session from thaTEC:Core’s menu bar:

The module might take some time to start. However, if any error message occurs or nothing happens, please update the support database as described here.

After the startup of the remote support module, the following window will appear, waiting for our remote access:

After connecting to your PC, you will need to grant access to your PC via the following window which will appear and will remain during the whole session allowing, e.g., to write text messages and stay in touch during the remote session:

Important note: During the remote support session, we will only have control over your mouse and keyboard as long as you are not using it. Thus, please do not use the accoring PC for other tasks during a remote support session!

Problems with reading/writing files

1) Is your file path to long? (Path length is restricted to 260 characters by Windows)
=> Solution: Try to copy file to another location / change file path

2) Check file or folder names for special characters

 3) Accessing the data file with, e.g., the thaTEC:DataInspector during the measurement can cause issues due to the simultaneous file access.
=> Solution: Check your live data only via thaTEC:OS !

How can I see the changes if an update for a software module is available?

It is possible to open the current changelog of the module before installing the update. For this, just right click on the respective module and select “Update” => “Open updated changelog”

Issues updating thaTEC:Core

In the latest versions, we changed the self-update procedure of thaTEC:Core. Thus, if you are using an older version (before 2019-08-06), the update is not always performed correctly and it might  still be indicated that a new update is available. In this case, please download the Core_updater module from the module library and run this module to manually perform the update.

The min/max values in scan definition in thaTEC:OS are not correct

During the connection process of a driver module to thaTEC:OS, the min/max values for each control are obtained from the properties of the individual controls and transmitted to thaTEC:OS. If the min/max values in the scan definition are not correct, there are possible origins.

1) The min/max values of the control were changed during the program runtime after the connection to thaTEC:OS. In this case, the properties need to be re-sent using the properties.vi. Please see also the example in the programming template (current range control).

2) Check the representation of your control. For example, currently, single precision (SGL) values are not recognized, thus, please change the representation of the control to integer or double precision.

Connection error to thaTEC:OS

Device module cannot connect to thaTEC:OS

=> Solution: Check connection settings in thaTEC:OS and in the device module via the menu bar > Communiation > Settings. If thaTEC:OS and the device module are on the same PC use the same PC setting.
