Access Denied to Registry Path

Irrespective of the current setting of “Load User Profile” in the IIS application pool, attempting to switch it to the inverse value and refreshing the pool might resolve the issue. However, the problem recurred later, and we discovered that setting “Load User Profile” to “False” in the IIS application pool settings resolved the problem once again.


Solution 1:

Executable

To access

HKEY_LOCAL_MACHINE

in the registry, you must elevate your privileges to at least

Power User

or run the executable

As Administrator

from the

./bin

folder. Another option is to disable

UAC

, but this may cause difficulties in Visual Studio unless you have one of the other options configured.

It should be noted that attempting to utilize

Run.. -> regedit

will result in a prompt for UAC, indicating that this restriction is not solely applicable to your application but to registry access in general.

Inside Visual Studio

To modify the registry through code, simply launch Visual Studio before

Run as administrator

.

Application manifest

To prepare for future use, consider generating a

app.manifest

and configuring your application to consistently demand administrator privileges. To do so, right-click on your project located in

Solution Explorer

and proceed with

Add -> New Item... -> Application Manifest File

. Once the application manifest is generated, modify the corresponding line within it.


to line


Starting now, the system will consistently ask for UAC permission if the program is not launched as an administrator. In case you execute

Visual Studio

without administrative privileges, it will try to restart the IDE as an administrator and request confirmation before continuing.



Solution 2:


To avoid the security concern of granting elevated privileges, altering the permissions on the registry key is another option. Use Regedit to open the key, then right-click and choose ‘Permissions’. You can either add the profile used by your application (such as a service account) or select an already-existing group (such as Users) and give them complete access. This method doesn’t require granting elevated privileges, making it a viable alternative solution.
