What causes ClickOnce URLDownloadToCacheFile failed during installation?

I'm getting the following error when installing my ClickOnce application via firefox. It doesn't happen with IE on the same computer. I swear I've installed it via firefox before. This is a Windows 7 machine.

The following is the howto from Microsoft, but this doesn't apply to firefox. There is no redirection happening either.

If a user has set Internet Explorer Advanced Security option "Warn if changing between secure and not secure mode" on the deployment target computer, and if the setup URL of the ClickOnce application being installed is redirected from a non-secure to a secure site (or vice-versa), the installation will fail because the Internet Explorer warning interrupts it.

Internet Explorer calls either LaunchApplication or ShOpenVerbApplication procedure from dfshim.dll behind the scenes, whereas Firefox plug-in (as well as a standard bootstrapper created by Visual Studio 2008-2010, which could also produce this rare error) uses a different, out of date technique to launch ClickOnce applications. (Note, that LaunchApplication requires at least .NET Framework 2 SP 2.)

To avoid such error one could redirect Internet Explorer to a deployment manifest (.application) and all other browsers to a custom installer (.exe) that would install .NET Framework if necessary and then call ShOpenVerbApplication.

Hmm, after using IE to install, then uninstalling, I was able to install via firefox again. Odd.

The following worked for me:

Within the local distribution package CLICK ONCE a web.config file was generated on line clientCache that was the problem, in which altered as follows for CHROME and IE8 and now run the file:

<clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="1.00:00:00" />

I've had this and it to resolve it was to disable the firewall. I sadly don't know what Firewall settings it was, I just disabled the lot and it ran/installed without issue.

After exhausting firewall options on this issue, I found that my excutable was pointing to the IP Address of the Application Server. When I changed the site deployment and consequently the executable to the FQDN of the server instead of the IP Address, the installer worked first time.

Simple Solution, on cmd execute setup.exe /URL=http://< Production  URL>/

Easy!
