Question Error using a DLL after installing it with a Setup project

[danicoelho7]

Hi,
I'm using VB.NET with VS 2008.
My program used a DLL when called.
This program is installed on the target computer with a Setup project.
After the instalation, when using the function that calls the DLL I get the following error:
HRESULT 0x8007007F.
On my computer it works, but when I install it on the target computer it doesn't.
The DLL is on the program folder.
How can I find the error?

Regards,

Daniel Coelho

Is this DLL a .NET assembly, a COM component or a standard binary library?

It is a normal DLL.
I wanted to compile some code in C, so I used the National Instruments LabWindows CVI to compile it into a DLL.
Maybe the problem is that I used LabWindows.
Maybe I should use Visual C++ to compile this C code into a DLL...

I would guess that the issue is more likely the DLL having an issue rather than your app.

You're correct.
I've tried another method to do the same thing and the program works fine.
I guess I have to examine the DLL code.
Thanks for your time.

Best,
