I've started to get this message:
"RUNDLL Error loading btwizard.dll The specified module
could not be found."
I haven't yet pinned down what activity actually triggers the message. But I do know that the problem has arisen since trying to uninstall a program. (I think it's now irrelevant, but FWIW that was called Desktop Capture Engine, which came as part of SUPER, the video converter).
I used the normally very reliable Revo Uninstaller. But somehow it deleted scores of files in \System 32 before I cancelled it.
One of the accidentally deleted files must have been btwizard.dll, which I found is owned by Bluetooth Software 18.104.22.1682 from Broadcom Corporation. I downloaded a replacement for that file, but the messages continued to occur.
Then I uninstalled Bluetooth Software (which I don't use - can't remember why I installed it those years ago and I don't pair BT devices with this desktop PC - or anything else for that matter). But I still get the message.
I've done the obvious stuff like running sfc \scannow and registry cleaning, and much googling.
I'll next try replacing btwizard.dll again in \System 32 (it was of course deleted when I uninstalled Bluetooth Software). But, as it's an intermittent problem, it might be some time before I'm confident this has fixed it.
Also, I remain nervous about negative impacts from the other deleted files. Would that sfc \scannow have replaced those essential to XP? Is there any way of finding what files were deleted? I backup data and my XP registry nightly, but not \Windows! And they were not in the Recycle Bin.
I'd much appreciate any insights or advice please. My PC seems to be running OK - I just close the message and continue. So it's not a serious practical problem, but I hate unsolved puzzles of this sort!
