Windows 7 is not supported yet so that may be one reason. However, open your setenv.bat script and look for JAVA_DIR. Where is it pointing? It should be pointing to C:\SoftwareAG\jvm\win160\jre or something similar.
If you’re still experiencing issues, you can open a ticket with support. Now, what’s interesting to me is that the error seems to be referencing a different path than what you have set in your JAVA_DIR (i.e. \Java\jre6 instead of C:\SoftwareAG\jvm\w64_160\jre). It could be an environment configuration issue.
If you look at your environment variables, do you have a JAVA_HOME variable set? Does your PATH include the bin directory of any Java installation directories? If so, you may try changing these variables so they point to your Software AG JVM installation. This may help pin-point the actual issue.
