ID: Q187282

The information in this article applies to:

Microsoft Visual Basic Standard, Professional, and Enterprise Editions, 32-bit only, for Windows, version 4.0

NOTE: The run-time files listed in this article are the core dependencies required by all 32-bit Visual Basic applications. Your application may require additional files based on the components you have included.

Visual Basic/Visual Studio 6.0
------------------------------

   MSVBVM60.DLL    6.00.8176
   OLEAUT32.DLL    2.30.4261
   OLEPRO32.DLL    5.0.4261
   STDOLE2.TLB     2.30.4261
   ASYCFILT.DLL    2.30.4261
   COMCAT.DLL      4.71*

* On computers running Windows 9x, the Internet Explorer 4.01 Service
Pack 1 Setup installs COMCAT.DLL version 5.0. Internet Explorer 4.01 
Service Pack 1 is installed in the first segment of the Visual Studio 
6.0 setup program.

NT 4.0 Service Pack 4
---------------------

   MSVBVM50.DLL    05.02.8244 (SP2)
   MSVBVM60.DLL    6.00.8244
   OLEAUT32.DLL    2.30.4265
   OLEPRO32.DLL    5.0.4265
   STDOLE2.TLB     2.30.4265
   ASYCFILT.DLL    2.30.4265
   COMCAT.DLL      4.71

The version of Msvbvm50.dll that ships with Service Pack 4 for Windows NT 4.0 is essentially the same as the version that shipped with Visual Basic 5.0 Service Pack 2 and Service Pack 3. The only difference is a change that was made to avoid a problem due to the new heap allocator in Windows NT 4.0, Service Pack 4. The version number is higher so that it will not
be overwritten.

Visual Studio 6.0 Service Pack 1
--------------------------------

   MSVBVM60.DLL    6.00.8268
   OLEAUT32.DLL    2.30.4265
   OLEPRO32.DLL    5.0.4265
   STDOLE2.TLB     2.30.4265
   ASYCFILT.DLL    2.30.4265
   COMCAT.DLL      4.71*

* Service Pack 1 contains COMCAT.DLL version 4.71, but Windows 9x 
computers that already have Visual Studio 6.0 installed will have 
COMCAT.DLL version 5.0 because it is installed with Internet Explorer 
4.01 Service Pack 1 during the Visual Studio 6.0 Setup.

Visual Studio 6.0 Service Pack 2, Vbrun60.exe
---------------------------------------------

   MSVBVM60.DLL    6.00.8268
   OLEAUT32.DLL    2.40.4268
   OLEPRO32.DLL    5.0.4268
   STDOLE2.TLB     2.40.4268
   ASYCFILT.DLL    2.40.4268
   COMCAT.DLL      4.71*

* Service Pack 1 contains COMCAT.DLL version 4.71, but Windows 9x 
computers that already have Visual Studio 6.0 installed will have 
COMCAT.DLL version 5.0 because it is installed with Internet Explorer 
4.01 Service Pack 1 during the Visual Studio 6.0 Setup.
