unknown explorer error

Using Win7 SP1 with Firefox 4 as kiosk browser. When Secure Lockdown is activated and system has rebootet i get following error [Unknown Explorer Version (6.1.7600.16768) can´t apply patch]. Any Ideas?

regards
Kai

sorry was Win7 without any SP.

Issue with disabletaskbarontop is not working when Update KB2515325 is installed. As soon as the Update has been removed everthing is working well.

Any issues with SP1 ?

thanks

This is caused by an Windows Update and only occurs on Win 7 64bit editions. To fix the problem, please remove the "KB2515325" Windows update using the Win 7 "Uninstall or change a program/View installed updates" feature. Currently this is the only way to remove the issue and the only problem when using Win 7 64bit

Did removing "KB2515325" cure the issue?

yes it solved the problem.

Okay. Thanks for the update.

I am having the same issue with win xp 32 bit but dont see that update installed in the computer.

Try selecting the "Disable Desktop" option in the Secure Lockdown settings.

that does it. tks :)
