application manifest errors

I'm getting the following error message at on one of my customer’s pc when installing an update to a deployment. All of my other customer’s are working fine. Has anyone experienced this issues or has seen this message?

"Reference in the deployment does not match the identity defined in the application manifest"

Here's Microsoft’s explanation.

I also saw somewhere in the past, that you needed to deleted the local internet cache on the client’s pc which was done. I've also uninstalled the click once app using add/remove programs. So I guess I'm not sure what to do. Here's the actual error:

Reference in the deployment does not match the identity defined in the application manifest.
