Jet Replication Object

hi! i'm installing my project when i encountered the following error: 'An error occurred while registering the file c:\windows\system\msjro.dll'

Any help would be appreciated.

Thanks!

The ActiveX DLL/Control isn't be correctly imstalled by the Setup Program

Which version of mdac_typ are you including in your setup. Since
this is part of the Jet ADO objects, it might not be included in
version 2.6 or higher.

The mdac_typ version i used in setup is 2.5.
Do you have any idea how i can resolve this?

And is it possible that i'm receiving this error message because the msjro.dll version i used in my project is different from the target machine?

thanks very much!

Is the version newer or older? If newer, there shouldn't be any
problem overwriting the older version.
What windows version is this?

hi! it's newer and i'm on windows 98 SE.
Do you think it's ok for me not to include this file -msjro.dll- on my setup? I've actually tried it and my program still works, but i'm still worried that it might not work on other machines.. what do you think?

thanks again!

Your newer version should be able to overwrite the older one, but
if the older one works ok, you probably don't need to worry about
it. Is it a separate file in your Setup.lst file, or is this from mdac_typ?

hi! u see i'm a newbie here so pls bear with me =)
on my setup though, there is a msjro.dll, and with regards to the mdac_typ, how am i suppose to know that it is included there?

thanks again!

Ok, sorry I didn't explain it better. If you were using the Package
and Deployment Wizard to make the setup, you could look at the
Setup.lst file and see if msjro.dll was included there as a single
file. You could also see if mdac_typ.exe was included. If this
error is coming from the mdac_typ.exe install, then there isn't
anything you can do about stopping it (other than to just leave
out the whole mdac_typ.exe from the install). If on the other
hand msjro.dll was in the setup.lst file, it could be removed from
the install altogether. Another thing is that if msjro.dll is in the
setup.lst file, it will have a version number. That version number
could be compared to the version number of the existing msjro.dll
on the target machine. If the install version is older, then it
shouldn't be trying to overwrite a newer one.

hi! Both msjro.dll and mdac_typ is in the setup.lst. Guess i'll just have to remove the msjro.dll since my program works fine without it. Though i'd like to ask, is it correct to assume that under the mdac_typ there is also a msjro.dll?

thanks very much thinker!

Yes, according to MSDN, it is one of the files that is installed from
mdac_typ.exe (as long as it is version 2.5 or less).

thanks a lot thinker!
your help is very much appreciated =)
