Windows Control Library Security

Question

Hello, thank you for your help
Im programming a website in c# and I have made a WindowsControlLibrary that can read the clients files (and is digitally signed). The problem is that for this to work the security on IE has to be set to Full Trust, however by default the security is set to a low trust which my clients cant change.

Currently the WindowsControlLibrary is not allowed to run at all and gives a compicated error my clients wont understand. I would like IE to ask the users if they trust the control and then if they click yes then the control gets access to read files from the clients machine. is there anyway to do this?

Thanks
