We hope one of the articles in our Knowledge Base helps resolve the issue.
If your licensing or installation problem still persists, please contact us — we are here and ready to help.

To help us investigate, please send the following information:

#01 - When was the last time it connected successfully? Has there been any recent system update on your side?

#02 - Have you tried using the Forgot Password option?

#03 - Screenshots of the error messages, together with a short description of what you have tried to do

#04 - Your dongle key number or your internet license username

#05 - The version of MIKE / update you have installed, or are trying to install

#06 - Has any SSL inspection or proxy server been implemented in your network?

#07 - The logfile generated by running DHISupportAssistTool.exe
(found, for example, in: Program Files (x86)\DHI\{Product-Name}\2025\bin)
Please note that the License Manager alone cannot generate this file.

#08 - Logfiles named NetLmLcw.log, NetLmLcw.log.0, and NetLmLcw.log.1, usually located in:
C:\Users\{user-name}\AppData\Roaming\DHI\LicSys

If you cannot find this folder, it may be hidden. In File Explorer: select View select Show tick Hidden items

You can also paste the following into the File Explorer address bar and press Enter: %AppData%\DHI\LicSys

#09 - If available, a logfile generated in DHI License Management by following the procedure described on pages 20 and 21 of the DHI License Management User Guide.

Please set the logging level to Info, re-create the error, then save the logfile by right-clicking and exporting it to a text file.

#10 - Logfile from: C:\ProgramData\DHI\LicSys\Relay\netlmrelay.log

If you cannot find this folder, it may also be hidden. In File Explorer: select View select Show tick Hidden items

You can also paste the following into the File Explorer address bar and press Enter: C:\ProgramData\DHI\LicSys\Relay

#11- For license locking/release issues only, please also send: C:\Users{user-name}\AppData\Roaming\DHI\LicSys\LicAdapter.log

Friendly tip for relay connection issues:

This issue can sometimes appear after system or Windows updates, particularly when using older MIKE versions. It may also be related to relay connection problems, SSL inspection, proxy/network rules, antivirus interference, or relay files not being read correctly.

If the issue seems related to the relay server connection, you may try the following temporary workaround:

Please try resetting the password in DHI Internet License Portal - Most of the time, it resolves the issue
Close all MIKE software, including engines and DHI License Manager.
If NetlmRelay.exe is still running, close it in Task Manager.
Delete this file, if it exists: C:\ProgramData\DHI\LicSys\Relay\netlmrelay.txt
Start a MIKE application again and check whether the issue remains.
