if you have installed the custo diagnostic server 5.X.X. and the custo diagnostic client 5.X.X. you can run the software in evaluation mode for 14 days.
After that you can decide to buy a license. In case you want to run the software in evaluation mode for another 14 days you can perform the following steps.
Stop the Tomcat server.
Open the directory where the database files are stored. The default location is: C:\diagserverdata\
Remove all the content in this directory
Restart the Tomcat server and after that start custo diagnostic client again. A new database will be created with another 14 days evaluation time.
WARNING! This can on;y be performed with a evaluation software and should NEVER be performed on server in a productive environment. It will result in data loss!!!!
