looks like error is coming from:
new FileSecurity(path, System.Security.AccessControl.AccessControlSections.All);

when you are executing it file does not exist yet.

You are right. I can confirm: this is the only problem. If this argument is omitted, it will work. You can post it as your answer.

Why doing it this way? What's wrong with creating reader or writer? (Asking just in case.)

if (!File.Exists(path))
{
File.Create(path, 1024, FileOptions.RandomAccess, new FileSecurity());

FileSecurity fSecurity = File.GetAccessControl(path);

fSecurity.AddAccessRule(new FileSystemAccessRule("Everyone",FileSystemRights.FullControl, AccessControlType.Allow));

File.SetAccessControl(path, fSecurity);

fileCheck = true;
}

Error is coming from:

new FileSecurity(path, System.Security.AccessControl.AccessControlSections.All);

You are trying to refer file that was not yet created.

I have same questions/doubts as Sergey: what are you trying to achieve? Is FileSecurity argument essential for you? Can you omit it?

(Just curious)

Thank you all for your kind and quick responses. FileSecurity argument is essential because without it I get another exception raised by lack of administrative privileges to read/write to files in C:// drive.
