You can run repair on IE or over-install IE to fix, as well as upgrading your Java will restore the file.
Repair IE5.xx
Control Panel - Add/Remove - highlight IE5 and Tools - click remove - click repair. If the repair option is greyed out or IE5 and Tools is not listed , use the over-install
technique
Over-install :
Close all in CTRL + ALT + DEL except explorer
Start - Run - IE5SETUP.EXE
(IE6SETUP.EXE if using IE6<- repair or over-install IE6 are choices given here.)
To over-install - Select Minimal/Custom - select ALL the parts you use,especially JAVA, over-install. Takes approx. 2 minutes normally, unless you added parts which need to download.
