Flash not loading in IE on client side

Hi, We have a perculiar problem. 1. We have done a flash menu which works fine on IE7 but client is not able to load on their company corporate systems (custom IE settings). They get some .cab error. 2. They have an existing website done by previous provider, which has a flash banner as well, and it loads ok for them. Just not our version's banner. Attached are screenshots of the error, [login to view URL] (previous version) and [login to view URL] (our version). [login to view URL] Need your help to fix the problem, perhaps tweaking the .js or .html embed commands. thanks
