In general with Java I have seen that the Java installer defaults to a 32-bit version of Java, but SnapCenter needs a 64-bit version of Java.
Open a command prompt and type: java -version
If the output does not mention it is a 64-bit version, then it is a 32-bit version.
You should install a 64-bit version of Java.
It has been requested to add a test to this to SnapCenter and provide a clear error message in the future.
Hope this helps,
John
