SQL Developer

Hi All.
I hope someone can help.

I have recently installed Oracle XE on my Vista Ultimate laptop and it is up and running with no apparent problems. I then connected to the HR schema on XE with no problems using SQL Developer 1.2.1.3213 (OLD Version). I noticed that SQL Developer 1.5.4.59.40 (NEW version) was available and downloaded it (the offering without JDK included) and renamed the "C:\Program Files\SQLDeveloper" folder holding the older version to "C:\Program Files\SQLDeveloper_Orig" and placed the new version of SQL Developer in the Prog Files directory to give "C:\Program Files\SQLDeveloper".

I then ran SQLDeveloper.exe (NEW) and when requested gave the JDK path as "C:\Program Files\Java\JDK_1.6.0_11\bin\java.exe" ('Java -version' gives 1.6.0_11-b03) and migrated over the settings from the previous version of SQLDeveloper (OLD).
The Application loads fine but when i attempt to connect to XE's HR schema i get the following error:

"IO Exception: Undefined Error
VENDOR CODE 17002"

I have searched to try and find out what is going on but cannot find any solutions that work. The previous 17002 error solutions on this forumn have all failed.
These included changing the JDK.conf file to hold route to JDK directory and also creating a 'bat' file.

My system does not have the directory for the JDK in it's PATH environment setting (either USER or SYSTEM) but does include a directory path under SYSTEM environment vars to another version fo JDK on my machine under "C:\Program Files\Sun\JDK\". I thought this may be causing a conflict but it is version 1.6.0.05_b13 and is also compatible-is it not? I also have Java JRE6 (1.6.0_12-b04) on my machine - this does not have a PATH variable and was not referenced when loading SQL Developer when loading the first time.

Can anyone help me resolve this, why can the previous version still connect OK to XE and not new version? is there something i am missing? Do i require the Java JDK Directory to be placed under a PATH environment SYSTEM variable?

Thanks in advance,
M
