what is solution for this issue?
i am also facing same issue.
I mention you're using the p6 professional / P6 Client. Which version/Release (P6v7.0, R8.0, R8.1, R8.2 or R8.3) with which Service Pack do you use?
Can you first check if the Claim Digger/Schedule Comparison is working? If not can you please check which JRE you have installed and if you have a environment variable JAVA_HOME set to your JRE-path.
