Deployment and Application do not have matching Security Zones

In my case (Microsoft Office 365 eDiscovery Export Tool), the error appeared when downloading the file with Firefox. I switched to Internet Explorer to download and start the .application file and then the installation succeeded.


This is wrongly tagged as a Windows 10 issue, when it is actually an issue that applies to all versions of Windows.

Deployment and application do not have matching security zones means there is a mis-match between the security settings in the deployment environment - i.e. your Windows O/S, and those embedded in the .exe application you are trying to run.

Detecting such a mis-match is a basic security feature, common to all versions of Windows (going all the way back to Windows 98). If the O/S thinks the program being run is a security risk, it isn't going to run it.

The answer to the question being asked, of course, is that there is no solution.

This error, in many (though not all) of its various manifestations, informs the user to contact the application vendor: this is because (and is an admission of the fact that) this error has no user solutions. It can only be resolved by the developer.

If you're getting the error, it means Windows doesn't think the developer has signed the manifests. The developer has likely failed, in the Signing tab, to check/tick the check box; and/or has failed to select a valid security certificate; and/or has failed to publish the software as Full Trust (but only as partial trust). (There are other possibilities too, but those are the obvious ones.) Such errors are developer errors, so can't be fixed by the end-user.
