http://en.wikipedia.org/wiki/Regsvr32 And see the links under "References". For some reason, sometimes DLL's will become unregistered and that can cause problems with the DLL and with the program(s) or function(s) that is required of it. Re-registering or registering it with that cmd line tool can fix it. The inverse can also be true. -Clint God Bless Clint Hamilton, Owner http://www.OrpheusComputing.com http://www.ComputersCustomBuilt.com ----- Original Message ----- From: "Harold B." I always find interesting how very knowledgeable people in news forums like PCWorks overestimate the level of knowledge of many asking questions. You say I answered the question myself. I don't even know what I am talking about :-) Of course I know how Run is used to access areas of my computer but what the regsvr32 is actually doing, and what it is doing vis-à-vis .dll files, I don't know. I know nothing about "regsvr32" except what I see in a search ... one is found in C:\Windows\1386, two are found in C:\Windows\Prefetch (I often see that "prefetch" and I don't know what that is either), and one is found in C:\Windows\System32. Other than the command Clint gave me, "regsvr32 c:\windows\system32\wups2.dll" I never used regsvr32 before. It just caught my interest making me forget about "Service Pack 3" - spending too much time in internet nonsense, I ought to spend more time in learning and not bothering you with basics. But then it's like driving a car; does one really have to know all the intricacies going on under the hood? --- Harold > From: "Clint Hamilton-PCWorks Admin" < > You answered that yourself Harold. > > "......and what I find is that regsvr32 is the command-line > tool that > registers .dll files as command components in the registry > along with a > lot of other information....." > > and, "but do see information that looks like it might go into > a cmd > window." > > Sorry but I don't know how else to explain it.
