IE C# ActiveX without permissons

Hi, I'm porting a VB ActiveX to C# .Net. The C# ActiveX is called from
IE as following:

<OBJECT id="myControl1" name="myControl1"
classid="ClassLibrary1.dll#ClassLibrary1.Class2" width="0" height="0">
</OBJECT>

The class is created and runs Ok until the following line

string path = Path.GetTempPath() + "Executable.exe";

Where it throws an Exception message like this:

"Request of the permission of type '
System.Security.Permissions.EnvironmentPermission, mscorlib,
Versino=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5....' failed"

What I have to do to grant the correct permissions for the assembly?

Thanks

Thanks! I read the entire thread but now I'm a bit confused. It's
possible or not to have the required permissions to execute the .Net
Assembly without change anything on the client side??
I don't understand why in VB the permissions are granted for the Win32
GetTempPath and not for .Net??
