Here's Ulrich's original message:

After installing Java 6.0.39(32bit) I get the message "Error opening registry
key 'Software\JavaSoft\Java Runtime Environment'".
The key CurrentVersion of the RegistryEntry is "1.7" (which is also installed).
I've installed several Java-Environements to my Windows 7: Java 6.0.39 (32bit
and 64bit) and Java 7.0.13 (64bit).
I'm not aware, how cygwin knows of these installations and how to setup Java. In
my personal '.bashrc' I've exported a JAVA_HOME and a modified
PATH-environment-variable. But I doesn't make any difference.

Ok; you didn't say that before!

My first guess is that it is not finding the same version of Java.
You can discover what bash will run with this command, in bash:
   type java

My second guess is that your cygwin is a limited privilege
environment that is not allowing the registry key to be accessed
for some reason. This goes beyond my knowledge of the details,
but there may be an export on the list with thoughts about it.
