Customers who have installed any Visual Studio 6.0 products such as Visual Basic 6.0 or Visual C++ 6.0 should install the latest Microsoft Visual Studio Service pack, as documented in the following article in the Microsoft Knowledge Base:

What Does This Update Fix?This update has the new C-Run-time Library DLL, Msvcrt.dll. which resolves the heap compatibility problems described in the following Microsoft Knowledge base articles:
190536The cause of the compatibility problems was a change in the internal layout of the way that the C Run-Time library allocates memory. No application should be dependant on this layout, but due to the issues in the previously mentioned articles, they are unknowingly affected by the new heap manager. The new Msvcrt.dll file implements two heap managers, the Visual C++ 5 compatible heap manager and the Visual C++ 6 compatible heap manager. It detects with which Visual C++ version your application is built and uses the appropriate heap manager for that application. If this version is 6.0 or greater, the Visual C++ 6 compatible heap manager is used and if it is earlier than version 6.0,the Visual C++ 5 compatible heap is used.
