Stdole2.tlb 2.40.4275.1 17.5KB (17,920 bytes)

In addition, the following files are also installed by Vcredist.exe. These are supporting files for the Vcredist.exe Setup program:

File name Version Size
Advpack.dll 4.71.1015.0 73.2KB (74,960 bytes)
W95inf16.dll 4.71.704.0 2.21KB (2,272 bytes)
W95inf32.dll 4.71.16.0 4.50KB (4,608 bytes)

Vcredist.exe supports the following command-line switches:
no switches = non-quiet mode, displays progress bar and reboot prompt
/q = semi-quiet mode, displays reboot message, and no progress bar
/q /r:n = no reboot message or progress bar
Vcredist.exe is not a full-featured installation package. As such, it is not a recommended redistribution method for the preceding files. This package does not communicate error messages back to the program or user that is starting Vcredist.exe. Therefore, Microsoft highly recommends that programs starting Vcredist.exe first check for available disk space (approximately 10 MB), read-only system files, administrator privileges, and a valid TEMP directory. The absence of any of these prerequisites can cause this package to incorrectly install some of the files onto the target system.

This package makes use of the 50comupd.exe utility to install the Comctl32.dll file. For additional information, click the article number below to view the article in the Microsoft Knowledge Base:
Q186176 INFO: Redistribution of Comctl32.dll
Because of this, the Vcredist.exe package cannot always determine if it is necessary to restart your computer (reboot), and it defaults to prompt for a reboot. If you are spawning this package with the quiet-mode switches /q /r:n, it is necessary for your Setup program to subsequently prompt the user for a reboot to ensure that the files are properly installed.

In addition, this package does not install any database components or localized satellite dynamic-link libraries (DLLs). For information about how to install database components such as ODBC, ADO, or DAO, please refer to the following Redistributing Microsoft Visual C++ 6.0 Applications article on the Microsoft Developer Network (MSDN) Web site:
http://www.msdn.microsoft.com/library/techart/redistribvc6.htm
For additional information about installing localized resource DLL's for MFC, click the article number below to view the article in the Microsoft Knowledge Base:
Q208983 HOWTO: Using MFC LOC DLLs
NOTE: This package does not install these components on computers that are running Microsoft Windows 2000 or Microsoft Windows Millennium (Me) systems. On computers that are running Windows 2000 and Windows Millennium, these components can only be updated through operating system updates and service packs for these operating systems.

Vcredist.exe can be freely redistributed with your application. You should also provide a copy of this Knowledge Base article.
