ClickOnce Store Metadata "AppType" Invalid

I have an application that uses ClickOnce deployment. It works on about a dozen machines except one. I am getting the following error. I found a solution from http://groups.google.com/group/microsoft.public.dotnet.distributed_apps/msg/42d44ffe781d3610 but it requires go to registry and remove AppType which is not the best solution because every time i have a new version, it won't work again.

Does anyone have any idea about this type of error and how to deal with it.

Many thanks.

Best regards, Vlad.
