isimSoftware ClickOnce Trust Prompt Behavior Tool
This free application allows you to configure the ClickOnce trust prompt behavior of your Windows operating system through a graphical user interface. This is more convenient and safer than editing the registry directly (with regedit.exe).

Start the tool by running the downloaded file (no installation required). It will read and display the current trust prompt configuration from the registry:

The trust prompt behavior can be configured for five security zones. You can make changes by selecting one of the following values from the dropdown lists:


Enabled: The ClickOnce trust prompt is always displayed. Users can choose if they want to trust an application or not:

Mobirise
AuthenticodeRequired: The ClickOnce trust prompt is only displayed for applications which have been digitally signed (same trust prompt dialog as above). Installation is not possible if the application is not signed with a valid certificate identifying the publisher:

Mobirise
Disabled: The ClickOnce trust prompt is never displayed. The message your administrator has blocked this application because it potentially poses a security risk to your computer is shown with no option to trust the application:

Mobirise
To write the values to the registry, click on the Write to registry button:

Mobirise
A confirmation is shown if the operation completed successfully:

Please note:

If a zone is not defined in your registry, the dropdown list will show an empty value as the selected item.

If your registry does not contain the key \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\Security\TrustManager\PromptingLevel, the application will display a warning. You can still use it to create the registry entries.

The trust prompt settings have no effect on already installed ClickOnce applications (and on their updates).



Administrator privileges are required to run this application (as it accesses the registry).
