I recently rebuilt my PC as it was getting clogged up with dross and did a clean install. Thought I'd backed up everything but now when I open one of my Click Once VB.NET applications in Visual Studio 2010 I get this error when I try to run or compile the application:
"Unable to find manifest signing certificate in the certificate store."
I have tracked this down to the "Signing" part of the Project properties where ther was a tick on "Sign the ClickOnce manifests". I can run the program by unticking this but want to know what problems this might cause. If the original certificates went west with my old PC is there any way I can get them back or regenerate new ones.
If I leave it with the "Sign the ClickOnce manifests" unticked and publish a new version will it still work for end users or is the certificate intrinsic to the way ClickOnce works?
