Heya.
Not too sure if you guys are watching this thread or not... but I ran into the same problem today and came across this posting... so for all those of you who run across this.. this is how I resolved the issue:
To tell the Publisher where to get the Certificate from:
1) From the Menu Bar, Click Project-> Properties
2) In the Project Properties, click the tab labeled "Signing"
3) Click the Checkbox labeled 'Sign the ClickOnce manifests'. This enables the sub-section (directly below the checkbox) where you can point to a certificate.
4) Click on the button labeled 'Select From File...". In the directory listing.. I found several .pfx files in my project directory. I choose a random one (ProjectName_TemporyKey.pfx). Click Open. You'll be brought back to the properties form again.
5) From the sub-section described in step 3, click the button labeled "More Details...". This will display the certificate you've selected.
6) Click the button labelled "Install Certificate" and follow the prompts.
7) Save Solution
8) Publish your Solution.
Hope this helps!
