The main issue here is previous uninstallation doesn't go fine; if some files are locked by some Java application/applet. This will cause failure in subsequent installation. We should not provide the option of ignore button, as this may lead in failure installation.

How to reproduce.
1.) Install JRE promoted b25
2.) Open some applet in IE
3.) Now launch JRE promoted b26
4.) It will ask to reinstall
5.) Proceed with the reinstallation, it will prompt attched dialog (FIU_Reinstall.JPG)
6.) Clcik on Ignore button in the above dialog
7.) It will start the installation of b26

Expected behaviour
B26 should have been installed without any problem

Actual Behaviour:
b26 installation is failing with erro 25025. (attachement - ErrorDialog.JPG)

The main reason of this error is
"HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\PendingFileRenameOperations" has lock for these files
