I' m creating a program to create documentation out of an XML schema.  This
program is written in Visual Basic and it creates a Word Document and an
Excel Document.

When I create a setup package with the Pack. and Depl. wizard, all works
fine on PC's that have Visual Studio installed.

But when I want to install the package on a PC that hasn't VS installed, I
don't get errors during the installation, but when the program starts and
the user presses the button, then I get a hell of a memory leak.  The
program has to be killed and nothing works :-(

I make use of a custom control (ocx), MSXML4, Word and Excel.

thanx in advance.

The installation of VS is probably the general cause but not the immediate
cause of the memory leak. The presence or absence of VS in and of itself
shouldn't cause a memory leak, but a specific issue in your code might,
depending on whether VS is installed. For example, if you use CreateObject
to instantiate an object from a component that's not installed on the non-VS
machine, and your errorhandling takes for granted that the object creation
won't fail, you might be in trouble. The package and deployment wizard could
easily leave out a component if there is no direct, compiler-visible
reference to it (as might happen when using CreateObject). API calls into a
DLL that's only installed with VS might also be a problem issue for the P&D
wizard, I'm not sure.

I hope some of that is helpful.
