Unfortunately the screenshots are a bit low res, so I cannot read anything on them. Did you use the installer to install STS 3.3.0 on your machine? And is everything 64bit (Windows, JDK, and STS, or everything 32bit, depending on your setup)?
In case you would like to check the JVM that is being configured for running STS, this is defined in the STS.ini file. Can you check that as well?
Marten is correct. You need to run STS 64bit with the JDK for 64bit (or 32bit each), but you cannot mix that. You can run 32bit stuff on your 64bit Windows machine, but you cannot mix a 64bit STS and a 32bit JDK. In your case I would recommend to run the 64bit JDK.
