Manual removal
Before you can delete it, the DLL file must be deregistered.
In BargainBuddy/Apuc, this DLL is inside the Bargain Buddy folder in 'Program Files'. Here there will be one or more 'bin' folders, one of which will contain a file called apuc.dll. If, for example, it's in 'bin2', the commands to enter (from a DOS command prompt window, under Start->Programs->Accessories) would be:
cd "%WinDir%\System"
regsvr32 /u "C:\Program Files\Bargain Buddy\bin2\apuc.dll"
(If your 'Program Files' directory has a different name (for example, on a non-English version of Windows), or is on a different drive, you'll have to substitute that in the path above.)
In BargainBuddy/Version, the file you have to get rid of is instead called 'CC_Versn.dll', and it's inside the 'Net2Phone CommCenter' folder in Program Files. The commands to get rid of it are:
cd "%WinDir%\System"
regsvr32 /u "C:\Program Files\Net2Phone CommCenter\CC_Versn.dll"
After the deregistration, end the 'Bargains' process from the Task Manager (ctrl-alt-delete). Having successfully done this you should be able to delete the entire 'Bargain Buddy' folder. To clean up the registry, run regedit and delete the value in HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run that refers to Bargain Buddy. You can also delete the key HKEY_LOCAL_MACHINE\Software\Bargains; in the Adp variant this is HKEY_LOCAL_MACHINE\Software\Microsoft\adp instead.
Partial installs
An installer executable may be included with the host application which attempts to download enough of the software to run so that it then updates itself fully. If this fails or has not yet run, you will only have the 'bargains' process. Kill this from the Task Manager (ctrl-alt-del) and remove the 'Run' value mentioned above, then you can delete the entire Bargain Buddy directory manually
