declares and "function not found"

hmmm… question…

One of our users is having problems with the 32bit version of our app running on Windows 10 64bit while using this very same library (although the initial loading is fine, the problem shows up in a later call)

I’m thinking that the VS2012 runtime may solve the problem he’s seeing with the 32bit version of our app.

The question is this: Should he download the vcredist_x64.exe or vcredist_x86.exe installer?

In other words, should it be the 64bit installer as he’s on 64bit Windows or the 32bit installer as he’s running a 32bit app?

or perhaps both?

vcredist_x86.exe if they are running the 32bit app
