SQL Developer v4 EA3 is working fine, but I decided to download the stand-alone SQL Developer Data Modeler because I had seen people recommending using it in favor of the one bundled with SQLDEV.
Windows 7 64-bit
Java (64 bit) installed into C:\Program Files\Java\jdk1.7.0_25
When I double-click the short-cut to start SDDM I get the following pop-up dialog error:
Title: Oracle SQL Developer Data Modeler
Unable to launch the Java Virtual Machine

I think I stumbled on the solution just prior to posting, so here is what worked for me in case anyone else runs into this....
I had created a desktop short-cut to "C:\Program Files\datamodeler\datamodeler.exe", which I am guessing is the 32bit version of the binary file.
I was able to launch successfully by pointing to "C:\Program Files\datamodeler\datamodeler64.exe"
