Trouble registering DLL

Hi all,
I wrote a program using VB with DTS features. When I port it to a client computer (Win XP Pro), it works well after I register the DLL manually using regsvr32 command. The same thing also happens in Win NT 4.0 PC. But when I try to install it on other PCs using Win XP or NT 4.0, it doesn't want to register. Everytime I run "regsvr32 dtspump.dll" the PC always returns "Load ("dtspump.dll") failed......."

Can anyone help me? What shoudl I do to register those DLL?
Thanks a bunch.

On the computers that are returning the error, have you ensured that COM+ (in the case of XP) and MTS (in the case of NT 4.0) are installed and running? I am assuming that you are using XP Pro?

Also, don't worry about registering it with the regsvr32 command. If it is a true transaction component then it will register itself when you drop it in the package for component services, although you will have to put it in a static directory as well (do that first, then drag and drop it into the Transaction package)

Let me know if this helps. If you want, you can message me with more specific information about the component.

Thanks for your answer.
But how do I check whether MTS are installed and running?
I checked on the "Services" but it wasn't there.
Could you please explain?

Thanks a lot.
