Hmmm. I don’t want to tell you something wrong since I don’t fully recall the process and I don’t have an AS installation to verify, but I think you had to remove the hw files installed in the AS folder…
Not sure if you also have to remove it from some xml… If you feel comfortable you can just try. (e.g. just rename the folders / backup the xml). If not wait a bit and probably someone from B&R can provide a small guide.
