Help Needed with .Net dll in vb 6

Hi,
I am having a C# .net dll which I am using in VB 6.
Now everything works fine. The exe can be started from 2 places.
1.Directly
2.From a Lauching app.

Now when I run it directly, it works fine. But when i run it from the Launching app it gives an error. Object Not Set error 91.

Another thing is that on few machines it works fine but problem comes in 2 machines.

Tried with register and all stuff.

Can anyone suggest something.

Thanks!

are you using this thing? https://www.microsoft.com/downloads/...displaylang=en

No I am not using that.

In fact I don't have a form here.

Another thing is that when I put both the exe's in one folder it works. There is also a differen. Let me say A.exe is calling B.exe

When I have A.exe copied to B.exe folder then it works fine.
But when I copy B.exe to A.exe folder then it doesn't work.


Thanks!

Have you copied the dlls used by your executable too ?

All dlls that are referenced by the exe have to be in the same folder as the exe when running it.

It looks like working folder of the VB app is messed up when your VB application is launched from the launcher application. Check the working folder. If this is the case, review the code in launcher application.

You need .NET runtime environment to use the .NET dll in your VB 6 application. Check those machines that give problems and see whether they have CLR in them.

The App folder is not messed up. The application starts fine. Its only creating problem at the point were .net dll call is made.
The application opens from both places.

I am sure that all machines have the CLR installed. I can run other Apps on that machine.

Thanks!
