Java web start JRE auto-download does not work in vista.  The JNLP jre installer can be download and launched, but when we do a Runtime.exec on the jre installer itself, the create process failed:  (even a standalone java application that do a Runtime.exec on the installer fail too)

execute !C:\jre59234.dat /s /v"/qn WEBSTARTICON=1 INSTALLDIR=\"C:\Program Files\
Java\j2re1.4.2_07\\""!

java.io.IOException: CreateProcess: C:\jre59234.dat /s /v"/qn WEBSTARTICON=1 INS
TALLDIR=\"C:\Program Files\Java\j2re1.4.2_07\\"" error=740

EVALUATION The error code 740 is probably returned by CreateProcess WINAPI. 740 code: ERROR_ELEVATION_REQUIRED: The requested operation requires elevation. I guess we cannot invoke any exe we want in Vista with medium integrity.

EVALUATION at firsts I thought it's because of the file name we use: jre59234.dat since you cannot really run that in Vista directly (double click on a .dat file won't run it). But then even if I changed it to jre59234.exe (with this you can now launch in Vista), runtime.exec on it still fail in Vista. More investigation needed. *** (#1 of 1): [ UNSAVED ] ###@###.###
