 ERROR com.appian.komodo.engine.KLicenseVerifier - Error starting K: null 
 As per the possible solutions mentioned in the KB article, 
 I have already: 
 
 Requested and applied a new long team license to my local instance. 
 Verified that there have been no changes in the following:
 
 The operating system. 
 The CPU count. 
 The Fully Qualified Domain Name (FQDN). Ensured that no more than one hostname resolves to the local network IP of the machine where the license is installed.

Without more information, all I can say is that the most common error is the FQDN and memory in my experience. 
 Otherwise. perhaps it is in the wrong location.
