Your wyBuild is a great product and I love to see below features implemented in your future releases.
1. add *.bat execute support after finishing updating (wybuild 1.2 only supports exe and com at the moment.)
Good idea, it'll be in the next version.
2. add force update option : e.g wyupdate.exe -f (bypass client.wyc and server version check)It's very helpful when my clients deleted some files accidentally or they're corrupted. He/she just needs to run wyupdate.exe -f to re-download all files from the server.
Something very similar is already included in wyBuild 1.2. As it is now, when wyUpdate is patching your product, if it detects something wrong it downloads the full version of your product. Here's the option in the wyBuild project properties window:

Is this what you're suggesting, or are you talking about re-downloading an existing corrupt version?
