IE 10 and software restriction

Hi,

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

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

WTF ? I'm trying to run C:\Program Files (x86)\Internet Explorer\IEXPLORE.EXE and apparently denied C:\Program Files\Internet Explorer\IEXPLORE.EXE which in turn runs fine....

It was OK in IE9

My software restriction policy is

- "everthing disabled"

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