Hi all,

I have just opened a project I completed a while ago in Visual Studio and I am suddenly getting a build error with the following message:
Unable to find manifest signing certificate in the certificate store.

Can someone tell me what is causing this and how I can sort it out?

Many Thanks

Have you changed your pc/laptop since you last opened the project?

The certificate which was used to build and sign the project is no longer available on your pc/laptop. It maybe that it does exist but has expired.

You either need to restore the lost certificate, or simply create a new one and sign the project with the new certificate.

Not sure how your using the certificate in your enviroment. I have a domain wide security setup file which allows all full network access to any of my deployed .net apps which are signed by my certificate. if i lost the certificate it would be bad.

If you only used it to sign the published app, just create a new one.

I have this problem, and it seems to be caused by the publisher.
To solve my problem I had to uncheck the "Sign the ClickOnce manifests" check box on the project properties window at "Signing" TAB.

Hope this helps. Regards,
