Error 193 loading external

Anyone have information on what could be causing my standalone app to report "Error 193 loading external XXXXX" in the Max Console on a Windows machine, where XXXXX is one of several 3rd party externals I'm using?

The app works correctly on many different machines, it's just this one that's giving this error. The OS is Windows 10 64-bit, the app was built with Max 8 so is 64-bit, and all of the above externals are also 64bit, and as I said working fine on other machines.

Stumped!

Probably missing older vcredistributables DLLs.
Had same issues once, copying msvcp and msvcr DLLs
100, 110 and 120 into standalone folder fixed it.

Thanks - and yes this is my line of investigation so far. It's a standalone that I distribute to others, and I bundle the 120 (Visual Studio 2013) files together with my app, so I know it's not that one. I've started testing sending the user the 140 file (Visual Studio 2015) first, if that doesn't work will try the others as well.... For my own help when I refer to this thread in the future (!), this is a very good thread in terms of info mapping the number of the files to the VS version: https://cycling74.com/forums/standalone-missing-msvcp120-dll-on-windows
