I have problem installing Service Desk 7.4

After installing the software, I configured database(MySQL), tested the connection and it showed success message, when tried to save the configuration I got error "could not execute query". When I checked the logs I found statement
Code:
"Table 'servicedesk.version' doesn't exist"
, then I tried created all the tables manually but even that didn't helped. What should be the problem, anyone has ideas, please share it.

Additionally I got below exceptions at application startup, anything related to this?

Code:
SEVERE [localhost-startStop-1] org.apache.catalina.session.StandardManager.startInternal Exception loading sessions from persistent storage
 java.lang.NullPointerException
