In those instances when I am not sure of the nature of the file I want to delete, I first rename the file extension ( .xxx ) and see what happens for a while before deleting the file. From other forum discussions, the apparent solution to your problem was to edit out the reference to the file in the registry and then, restarting the computer in DOS, delete the file itself. See http://forum.osnn.net/showthread.php?t=9872 and http://www.mcse.ms/archive65-2004-6-760956.html . Sorry you had to reformat the HD and reinstall the OS. That is a lot of work.

Having no idea what program was associated with it I did a search for the named .dll I found it as a solitary file in a sub-folder of Windows, maybe System32. Long story short is I deleted it and had to reformat and reinstall the OS because Windows would not completely load. Prior to deleting, a Google search for this DLL only produced message boards with comments stating to reinstall the OS but no other explanations, especially what would occur if it were simply deleted and no mention of which program it is associated with. Is anyone here familiar with this DLL, the program it would be associated with and the problems that occur secondary to its deletion? Word of caution: DON'T DELETE THIS DLL UNLESS YOU HAVE BACKED UP ALL YOU WANT TO SAVE AND ARE PREPARED TO REFORMAT YOUR HARD DRIVE!!
