IE 10 upgrade - software restriction policy issue

Hi,

Following the upgrade to IE 10, IE10 x64 runs fine bur IE10 x86 can 't be started :

"Access to C:\Program Files\Internet Explorer\IEXPLORE.EXE has been restricted by your Administrator by the default software restriction policy level."

It was OK in IE9

My software restriction policy is

- "everthing disabled"

- Additional rules to allow %programfiles% and %programfiles(x86)%.
