WebStart Install Fail

I had 7u10-b18 32-bit already installed when this failed.  The fix was to
manually install the 64-bit-bit JRE.
Filed RT-26964 <http://javafx-jira.kenai.com/browse/RT-26964> without using
the word pathetic - that was directed towards the situation not any people,
sorry for that.  I think we can all agree that it was not a good user

I can think of only one "weird" thing about my environment that might have
triggered this.  I had 32-bit 7u10 installed AND I made sure that the
32-bit java.exe was copied into the Windows System32 directory instead of a
64-bit java.exe.  Normally on 64-bit windows the 32-bit java.exe isn't
copied there, but the 64-bit version is.  As we use a lot of 32-bit JNI
DLLs the 64-bit java.exe being on the path ahead o 32-bit java causes all
sorts of frustration during development.  I'm going to uninstall 64-bit
7u10 now and see if I can reproduce the problem again.  It happened
consistently before installing the 64-bit JRE.
