IIS7 Failed to grant minimum permission requests

Question

I get this error when I\'m using FileHelpers.dll, but my IIS is set to Full trust level so it should not be that way

That\'s the full stack trace:

Answer 1

We had a similar issue with Windows 2008 R2 where our application would work fine in 64bit mode but when switched to 32 bit mode would cease to function and throw the permission error, turns out, in IIS7 under Advanced Settings >> Process Model >> the "Identity" setting had been switched to "Application Pool Identity" by default and may need changed to "Network Service" to work in 32 bit mode.

We did that and now we are humming along smoothly. Figured this tidbit of info may be the reason that everyone points to folder permissions, because technically it is a folder permission issue. But the change was in IIS and not the security settings on the folders themselves.
