• Your internet security is preventing Create from installing correctly.
• Add www.presentationsolutions.eu to your trusted domains list.
Note: Sometimes this error occurs due to the file location rather than the computer not trusting the certificate. For example, if trying to install the file from the folder C:\. By default this folder location would be trusted, but the most likely reason for the error message is that the security settings on that machine prevent ClickOnce from installing from there.
If you wish to install Create from local files instead of from our server then you need to ensure that where you put the installation files is trusted. If you wish to check your settings, here is the key containing the relevant security settings: \HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\.NETFramework\Security\TrustManager\PromptingLevel\MyComputer. The value should be “Enabled” to allow a signed ClickOnce package to install.
