An unhandled exception of type 'System.Security.SecurityException' occurred in mscorlib.dll
Additional information: Requested registry access is not allowed.
 

This problem occurs because the user account that we used to create log does not have sufficient permissions.

 

We can solve the problem by 2 solutions below.

1. Add an application pool on IIS
    Change the default setting of this application pool.
    In Identity tag: change predefined value "Network Service"  to "Local system"
    Set  appMail service app to use this application pool.

 

2. Give the ASP.NET user permission to read from the event log registry entries.
Select Start - Run, then enter: regedt32

Navigate/expand to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Security

Right click on this entry and select Permissions
Add the ASPNET user
Give it Read permission
