When invoking the DT-enable public sample apps with the the existing jre 7, there is a " ERROR deleting file" with error code 5 popped up at the end of JavaFX 2.0 Set up


*** Tested Configurations:
- x86 XP, x86 Vista
- jre 7-fcs
- public fx sample (b39) installed locally

*** Steps to reproduce:

0) Install jre7-fcs
1) Get b39 promotion fx public samples and install on the local machine
2) Make sure that no javafx runtime installed
3) Using any browser to invoke the public sample from step 1)
(ex: C:/fx/javafx-apps-2.0-beta/experiments/BrickBreaker.html)
4) Follow the instruction to download and install Javafx runtime

At the end of the installation, if there is a "ERROR deleting file" dialog- (see attached screenshot), then the issue is reproducible

(Also, on a different issue, when the above problem occurs, it is very strange behavior as one tries to click on the webstart link to launch the same apps from within Chrome and IE browsers)
