InfoPath Dev

Hi, I'm still fighting with signing digital forms by normal users. I have noticed that normal users (without admin privileges) in Tools -> Manage Add-ons can't see DSigCtrl.dll on add-on list. After installing both components (DSigCtrl.dll and DSigRes.dll) as administrator, DSigCtrl has publisher set to: "(Not verified) Microsoft Corporation". Should I install some additional Microsoft certificate? Is there any option to run add-on with not verified signature?
Do you have the same publisher name?

I'm using Windows 7 / Vista + IE8 and Infopath Forms Services 2007.

The digital signature components are downloaded from these locations.

https://spsite/_layouts//1045/DSigRes.cab

 Does anybody know why they are different?

I haven't found any solution so far. Could anybody check if one of this files is located in '(Not verified) Microsoft Corporation' section'?
