Is the executable you are running on the other computers actually on that
machine or on a network drive? This can cause problems as the code is run
with less priveledges.

Nope, this not a Windows access rights issue, it's a CAS error message. It means that the
"code" is loaded from a location that has no FileIOPermissio ns in it's permission-set, that
means it doesn't load from a local drive but from a "network" drive.

The executable is ON that machine.
On WHAT machine, it's clear that the code is loaded from a *non* local drive, code that
loads from local drives run with full-trust, that means they have full IO access.
Willy.
Unless the CAS has been changed on the machines he's trying to run the exe
on so as to not give any code Full Trust (i've never delved into modifying
from the default settings installed).
If you're not the admin of the machines it could be worth asking the admin
if they have modified any of the .NET CAS settings in Control
Panel->Administrati ve Tools->Microsoft .NET Framework x.x Configuration.

IMO this is very unlikely, first the tool is no longer distributed with the V2.0 framework
(only included with the SDK or VS install), second , IMO the OP is the admin, do you think
he removed FIleIOPermissio ns from the fulltrust permission set?

It's loaded from a local drive. I've simply created the application, copied
to usb flash disc, then copied it from usb flash disc to the local drive on
the other computer (with windows Xp installed, and user logged as an
administrator, and where Total Commander works fine with full access to
drive C:\). And when I try to run this application I get this error. It
happens on all computers except mine. I found a solution to add a
certificate or sign the application with some key but it's to complicated
for me.
Emil
OK, I've solved the problem.
The security exception really occured at this:
DriveInfo[] Drives = DriveInfo.GetDr ives();
foreach (disc in Drives) comboBox1.Items .Add (disc.Name);
I've changed it to:
for (int i=0;i<Directory .GetLogicalDriv es().Length;i++ )
comboBox1.Items .Add(Directory. GetLogicalDrive s()[i]);
and now it works fine. Notice that string[] drives =
DriveInfo.GetLo gicalDrives(); would also throw Security Exception. Why ? I
don't know ;)
thanks for help anyway
