DLL import & executable into network drive

Hello,
I explain my concerns:
I developed a DLL that allows for different actions in PDMS. Unfortunately I encounter problems. When the dll is local, there is no problem. By cons when she is on the network, I have a following error:
Unable to grant minimum permission requests. (Exception from HRESULT: 0x80131417)

Do you have a solution?
thank you very much

U need to use caspol:
caspol.exe -q -m -ag LocalIntranet_Zone -url "file://ServerName/path/to/addins/folder/*" FullTrust -n CompanyName

Thank me_hungry

If  the DLL is installed on a path that I do not know in advance, so it is  impossible to run on a PC that does not have administrator access?

Every OS has its own security system, that disallow to run NOT ASSIGNED .dll from the network.
To allow this, U need to use [COLOR=#333333]caspol on users machines.[/COLOR]

Aveva PDMS uses caspol for example? because I did not encounter any problems when I copy / paste the folder to install to drive network drive network
