Found another problem with UpdateBuilder. I have a project with an executable in a CAB file and several other files that are uncompresssed. These are not included in the CAB as they need to be installed in a subdirectory of the application.
This works fine when using the UNC option, but with FTP only the executable and the first file is uploaded, subsequent files and the inf file are ignored.
Can you please provide some more detailed information as it is unclear how exactly your WebUpdate project & generated control .INF file is constructed. As this might contain sensitive information, it is best to provide this information by email so we can investigate.
