If you're getting this error when installing myLittleAdmin on IIS7:

Code:

Security Exception
Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Change your application pool setting "Load User Profile" to true.

Here is another explanation, when the virtual directory points to a remote share in ASP.NET

For those of you using myLittleAdmin from Plesk Install :
"Load user profile" must be true for "Plesk (Defaul)t (2.0) (Pool)"

Hi

I've got 32bit = true and load user profile to true but i still get an error.

we use SAN for cloud hosting so the files are on a network share. i executed this command to allow permissions to the san:

c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\caspol.exe -m -ag 1 -url "file:////\\enkompass-san\san*" FullTrust -exclusive on

the error from event viewer:

I tried emailing support a few days ago but did not get a response.

Hi Chris
Could you please send your email again at support [@] mylittletools.net

Remote-accessing your server could be interesting
