License load fails with "External exception E0434F4D" error
Posted by Yoni Davidson, Last modified by Yoni Davidson on 08 January 2018 04:09 PM

This error occurs when trying to load the license: 

EExternalException: External exception E0434F4D 


If the 2013 redistributable is installed, but the above problem still occurs, check if you have .NET 4.62  installed.

There might be a few other reasons for this error, even when  the VS2013 redistributor and .NET 4.62 are installed

  1. The machine is under a domain -> removing it from the domain just in order to generate the machine id might help.
  2. The FIPS security policy might be blocking this operation. Please disable FIPS and try this procedure again.


How to disable FIPS: 

  1. Click Start, type regedit in the start search box and hit enter.
  2. In the registry editor navigate to:
    • HKLM\System\CurrentControlSet\Control\Lsa\FIPSAlgorithmPolicy\Enabled 
  3. This registry value reflects the current FIPS setting. If this setting is enabled, the value is 1. If this setting is disabled, the value is 0.
  4. To disable it double click on the file and select 0.
  5. Restart the computer and check.
