We get the message can not load the assembly Sybase.Powerbuilder.Datasource.Db or one of its depencies (Access denied). 

I tried to use processMonitor to find out which dll could not be loaded but was not succesfull. We deploy a dll as a .Net assembly target. It is working on about 30 desktops.

How can we find out why this dll is not loaded?

 

Thanks

Eric

Hi Eric;

  Did you register the "Sybase.Powerbuilder.Datasource.Db" file in the GAC?

No, we have not registered any of the dll's.

Did you use an installer to install the run time or just copy over to the machine?

If the latter then you will probably need to register the dlls in the GAC.

Hi

You say that it is running on 30 desktops, does this mean that it works on them ok and is just failing on one?

Have you installed SQL Anywhere 12 can you prove that you can connect to the DB outside of PB?

Cheers

David

Our desktop programma connects to the same database as the .NET target and is installed on the same machine.

We are connecting to SQL Anywhere 12 on a Windows 7 machine.

It is a .NET assembly. We have a setup with Advanced Installer and are sure that all runtime dll's are installed.

Is there a way to find out on which dll Sybase.Powerbuilder.Datasource.Db depends? I now have had a look with ProcessExplorer but could not find a missing dll. 

Thanks

Eric

Hi Eric

I think we need a little more information:

1. What database are you connecting to?

2. How have you deployed your application?

3. Are you sure you have all the runtime DLLs installed?

Regards

David
