Visual C++ Redistributables

Mar 27 '14 at 10:34


I do not see any documatation in the notes or on the forum about the dependencies of the 32bit Activex DLLs (ver 9.5.0) on Visual C++ Redistributable?

Do I need to install any Visual C++ Redistributable on target computers and what version is required?


Sorry, if post appears twice. I don't see the original post after account activation!


The Chilkat ActiveX's are built using Visual Studio 2008 (VC++ 9.0).

This was chosen because it is the oldest version of Visual Studio that supports features required to pass certain security tests by Microsoft, such as /SAFESEH /NXCOMPAT.

The reason the oldest version of VC++ is chosen is because it is the most likely to be already-installed on any given machine. In other words, it will be rare to find machines without it (as opposed to building the ActiveX's with VS2013, for example).
