ADO Errors on NT

[Jeff Carlin]

I have a client whose NT4 box will not run an ADO-based VB6 app. Looking thru his uninstall log (St6unst.log), I find nothing that gives a clue. Everything was installed and/or registered.

The kind of errors encountered while running the app are:
430 Class does not support Automation...
3709 Operation is not allowed...

Is this a DCOM-type error? Doesn't NT automatically have DCOM, etc? Is MDAC involved?

We have lots of other clients running similar apps on NT boxes with no problems. Can anyone give me a clue???

Thanks

Hi Jeff,

I have the same problem before. It took me a while to figure it out.

Here it is:

I used ADO 2.5. When I use Package and Deployment Wizard. It pick ups ADO 2.1. Therefore when I install on the client machine, ADO 2.1 is installed.

The problem occurs because the program is compile with
ADO2.5. To fix this I installed ADO 2.5 on my client machine and everything work OK.

Please let me know if this can fix your problem. I am very curious to know.

Don't forget to mak sure you have Admin privs on an NT box when installing MDAC or it will all go South when you try to run the application. :(

Thanks, guys. According to my client, he does have admin privs.

I looked in the setup.lst file for this project (the list of distributed files) and "msado15.dll" is not in there. Is this a problem? The only "msado" file in there is "msadox.dll".

Additionally, what version of MDAC should they have? They are running NT4. I notice I have Ver 2.50xxx on my machine. Should I have them load that?

Thanks for your help. I am lost!

Ok, here's the latest...

Client definitely has the latest MDAC version on his machine. He also has the msado15.dll file. We are both going nuts!

Just a thought...if he installed MDAC as a non-Admin, would that make a difference? Sorry, just grasping for straws.

Anyone???

Trust no-one! If possible go yourself and install MDAC with admin privs or have someone you know is reliable do it. Most customers are lucky they find their way home each day :).
