I'm not sure whether this is in fact an XP problem, and am slightly worried it may languish fairly much unseen when it might be a more widespread problem, but here goes:
A program of mine has vanished from Add & Remove Programs since a couple of days ago. Its files are still there in the Program Files folder, and when I attempted a reinstall I got an error message saying that there was already one instance active on the system and that I'd need to uninstall that and restart before I could reinstall. Yet no sign of it in A&RP any longer, and my uninstaller programs can't see it to uninstall it! If I go through the Start > All Programs command and try and uninstall it that way, I get the error message I referred to, and can't uninstall.
Does anyone know if there's a way I can force A&RP to recognise it, or do you have any suggestions as to how I can uninstall, please?
It is an XP/SP3 computer, admittedly, although as I said above I'm not sure how relevant that is. The software is a program controlling a mobile broadband dongle.
