Do I need a special DLL for e-mail?

I have an old APP (v5) that had trouble when everyone got XP. Then I rewrote
a part and compiled it into v6. We don't do an install when we get a new
version, we just throw out the EXE on the network. But now, no one can do
the e-mail anymore. I can do it on my machine, and I am wondering if there
is some DLL that they don't have on their machines that I have. The code is
using MAPISESSION. I thought it might be the mapi32.dll, or I must have an
updated DLL (for V6) that they also need. Does this ring a bell for anyone?
Thanks so much for any thoughts.

Can you elaborate a little on "no one can do e-mail"? Are they getting error
messages, or is this about the NTSP2 security tightening?

Sorry, yes, I sounded like a user. There is an OLE error - "Invalid Class
String". Funny thing is that I can do it fine (without errors) and one other
user can do it fine too b/c she didn't get a new computer (but she does have
XP too). I am just not sure what to look for on the new computers. I
thought it was a system file that we had that no one else did but I don't
know much about those things. Thanks for any help.

OK, now we're getting somewhere. <s>

You say you don't do installation programs, so that could lead to this
problem. The VFP6 setup wizard automatically makes sure the target machine
has the necessary VFP *AND SYSTEM* DLL's. If I was guessing, I'm guessing
the newer XP machines don't have the older VC++ runtime files or something
like that.

Although, "Invalid Class String" seems fishy as an error message too. I was
expecting something more along the lines of "Class not registered".

Ok, so you think if I do a NETSETUP with the VFP6 that this might solve it?
I guess it is worth a try. Thanks for the thoughts.
