all these errors are caused by one fact that the filed downloaded by click once are “Broken”, either file is deleted or the signature is incorrect.( for example, you download the file from http://servera/, then next time same file is downloaded from the loadbalancer. http://loadbalancer/ or http://virtualIP/
Fix is easy. Go to the default once click app file location.
windows 7 will be C:\Users\[userid]\AppData\Local\Apps\2.0
xp or 2003 C:\Documents and Settings\[userid]\Local Settings\Apps\2.0
delete all those folders in that path.
try to install and run the app again, the issue will disappear. It looks like the pre-determined state of click once is broken.
