ClickOnce Deployment error : application validation didnot succeed

I have a winforms app deploying with ClickOnce.

But when i try to publish, this generates the error like application validation did not succeed, please contact application vendor.

Below given is the error in detail.

Application manifest has either a different computed hash than the one specified or no hash specified at all. File, Netspective Fluent XA.exe.manifest, has a different computed hash than specified in manifest.

I tried googling and several options stated, none of them helped, could anyone point out what will be exact issue.

I created a key and signed the manifest. But it still shows error.

Please guide me through!!!!

Thanks

@Herdo : i have tried this already. I created a project from scratch and tried the same, but failed. Also, tried to regenerate manifest. could you please explain the steps to do? I am running .Net 4.0. will that be an issue? - csLijo

Let me guess what's wrong:

Be sure that "Publishing Folder Location" or "Installation Folder" is the same as user see it. ClickOnce application can be launched only from one of these 2 locations. The problem you described can happen if you manually copied the files to different folder / server.
