InfoPath Dev

Hello

I am trying to turn on digital signature components for normal users (IE 8, Infopath Forms Services). They are installed from administrator account, normal users activate them:

menu Tools -> Manage Add-ons -> Show -> Downloaded controls

DigitalSignatures Control Class, State: Dislabled, click -> Enable
DigitalSignatures Resources Control Class, State: Dislabled, click -> Enable

And my results:

- Windows 7: OK, works

- Vista: OK, , works

- Windows XP: Error (translated from Polish): 'An error has occurred. Please try again.' Two buttons visible: Continue, 'Start from beginning'  

 Could anybody help with XP problem?  
 

Probably has something to do with the default IE security on your WinXP machines. Doesn't make much sense though since you are doing it from an admin account. Anyway, this is an IE issue, not an InfoPath one.
